Presentation. After replication resumes, it will log an event ID 4602 that indicates that DFS Replication initialized the SYSVOL replicated folder and specified it as the primary member. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Bur Flags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. What you need to do SYSVOL is still replicated by FRS for failback. Open server manager and look in event viewer > application and service logs > file replication service. If this event occurred during the migration of SYSVOL from File Replication service (FRS) to DFS Replication, changes will not replicate out until this issue is resolved. But dfsrmig can also give you an overview of your architecture's overall state before you actually start migrating. 3 (eliminated). Replication is multi-master, i.e. To test the former, use the RepAdmin command line utility (with /showrepl /all or /replsum switches). You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line … Start the DFSR service on the other non-authoritative DCs. You want to force the non-authoritative synchronization of sysvol replication on a domain controller (DC). This can cause the SYSVOL folder on this server to become out of sync with other domain controllers. FRS is deprecated. You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. Set the DFS Replication service Startup Type to Manual, and stop the service on all domain controllers in the domain. How to perform a non-authoritative synchronization of DFSR-replicated SYSVOL (like "D2" for FRS), In the ADSIEDIT.MSC tool modify the following distinguished name (DN) value and attribute on each of the domain controllers that you want to make non-authoritative:CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=FALSE. State 0 b. Force Active Directory replication throughout the domain. You will see Event ID 4114 in the DFSR event log indicating SYSVOL is no longer being replicated. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. If only repairing one DC, simply make it non-authoritative and do not touch other servers. That domain controller has now done a D4 of sysvol replication. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line tool to achieve this. That domain controller has now done a “D2” of SYSVOL. 11) Force the AD replication using, repadmin /syncall /AdP. a. Run the dfsrdiag pollad command on the second domain controller to trigger it to complete initial sync (event ID 4614). You will see Event ID 4614 and 4604 in the DFSR event log indicating SYSVOL has been initialized. 14) Start DFS service on all other Domain Controllers. For instance, this command will force push replication of all partitions while ignoring the schedules (this is a rather sledgehammer example): Repadmin /syncall /force /APed Furthermore, DFSR SYSVOL only replicates when AD has an open schedule (DFSR does not know about change notification). Windows Server 2003 b. previously if this is a disaster recovery scenario on all DCs in the domain. If changes occurred on multiple controllers, the last change will take precedence. Force Active Directory replication throughout the domain. But at least I saw that the service responded (although I had already had a confirmation about that with the command NTFRSUTL VERSION). You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. That domain controller has now done a “D4” of SYSVOL. Windows Server 2003 and 2003 R2 uses File Replication Service (FRS) to replicate SYSVOL folder content to other domain controllers. (Choose all that apply.) You move the DCs through these stages or states, by using the DFSMig command. This article is designed with a 2-DC environment in mind, for simplicity of description. If you want to force sysvol replication between two domain controllers in an active directory then use the below procedure. FRS is deprecated. Original KB number:   2218556. To be sure, run following command on one of your DCs: dfsrmig /getmigrationstate . After deep investigation, we found that is problem with DFS replication of SYSVOL folder. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. It also assumes you have the ability to restore data that was deleted, overwritten, damaged, and so on. Force Active Directory replication throughout the domain. NTFRSUTL FORCEREPL Command-Line Option to Force Replication. Once the migration to the ‘ELIMINATED’ state is complete, ensure that the old copy of the ‘SYSVOL’ folder that was being replicated by FRS is deleted. If only repairing one DC, make it non-authoritative and do not touch other servers. Original product version:   Windows Server 2012 R2 The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR. You will see Event ID 4114 in the DFSR event log indicating SYSVOL is no longer being replicated on each of them. Active Directory replication is different from SYSVOL replication using FRS or DFSR, although both use the replication topology and schedule from AD. Force SYSVOL Replication with File Replication Service (FRS) DroidFedo Monday, March 31, 2014. ..... PRIMARY-DC01 passed test FrsEvent Starting test: DFSREvent ..... PRIMARY-DC01 passed test DFSREvent Starting test: SysVolCheck ..... PRIMARY-DC01 passed test SysVolCheck Starting test: KccEvent ..... PRIMARY-DC01 passed test KccEvent Starting test: KnowsOfRoleHolders ..... PRIMARY-DC01 passed test … In this movie we show how to fix SYSVOL replication if it stops working with an Authoritative DFSR Synchronization. You will see Event ID 4114 in the DFSR event log indicating sysvol replication is no longer being replicated on each of them. As an administrator you may make a group policy change on the domain controller running the PDC emulator and you want this change to be replicated out to a branch location immediately. You will see Event ID 4602 in the DFSR event log indicating SYSVOL has been initialized. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe … This is unnecessary in most cases, and it may cause data loss if done incorrectly. This diagram shows the high-level steps which we will go into more detail about. Function Get-ADGPOReplication. A subscription to make the most of your time. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. If you had more than one affected DC, expand the steps to includeALL of those as well. This article is designed with a 2-DC environment in mind, for simplicity of description. Sonar.exe is a graphical tool that allows administrators to monitor key statistics and status about members of a file replication service (FRS) replica set. The specified domain %1 is still using the File Replication Service (FRS) to replicate the SYSVOL share. Modify the following DN and single attribute on all other domain controllers in that domain:CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=TRUE, Run the following command from an elevated command prompt on all non-authoritative DCs (i.e. 2. FRS will continue the replication of its own SYSVOL copy but will not involve with production SYSVOL replication. Open server manager and look in event viewer > application and service logs > file replication service. If you upgraded from Windows 2003 domain, there is a big chance that you are still using FRS (File Replication Service). Find out if your domain SYSVOL replication is run by FRS or DFS-R If ... (Distributed File System Replication). Get-ADGPOReplication is retrieving the GPO version and Sysvol version accross the domain for one or more Group Policy objects. Look at the file replication events of all your domain controllers for replication errors. c) Force Active Directory replication on a domain controller. Therefore, if you want to remove it entirely, you must do so manually. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. 14) Start DFS service on all other Domain Controllers. Windows Server 2008 c. Windows Server 2008 R2 d. Windows Server 2012 R2: b. On the same DN from Step 1, set:msDFSR-Enabled=TRUE. Furthermore, DFSR SYSVOL only replicates when AD has an open schedule (DFSR does not know about change notification). 11) Force the AD replication using, repadmin /syncall /AdP. Thereafter, it sets the ‘ SysvolReady ’ registry key back to ‘TRUE’ (1). Both 2008 and 2012 continued to function with FRS SYSVOL replication, but with 2016 and above, people using FRS will not be able to introduce a new domain controller into the Active Directory environment. To verify your DCs are using FRS and not DFSR, you can use this command: You want to force the non-authoritative synchronization of SYSVOL on a domain controller. 15) Search for the event 4114 to verify SYSVOL replication is disabled. File Replication Service – FRS FRS is a multi-master, multi-threaded replication technology. Run the following command from an elevated command prompt on the same server that you set as authoritative: You will see Event ID 4602 in the DFSR event log indicating sysvol replication has been initialized. The 9 DFS-R States. To improve the performance, scalability and reliability of SYSVOL replication, use DFS Replication (DFS-R) to replicate the SYSVOL folder, which stores Group Policy objects and logon scripts. For instance, this command will force push replication of all partitions while ignoring the schedules (this is a rather sledgehammer example): Repadmin /syncall /force /APed. The DFS Replication service initialized SYSVOL at local path C:\Windows\SYSVOL\domain and is waiting to perform initial replication. To test the former, use the RepAdmin command line utility (with /showrepl /all or /replsum switches). If this event occurred during the migration of SYSVOL from File Replication service (FRS) to DFS Replication, changes will not replicate out until this issue is resolved. The specified domain %1 is still using the File Replication Service (FRS) to replicate the SYSVOL share. 15) Search for the event 4114 to verify SYSVOL replication is disabled. But dfsrmig can also give you an overview of your architecture's overall state before you actually start migrating. Change msDFSR-Enabled to True. The process, detailed in KB article 2218556 "How to force an authoritative and non-authoritative synchronization for DFSR-replicated SYSVOL (like "D4/D2" for FRS)," reinitializes DFS Replication if SYSVOL is not shared on domain controllers. This means that as soon as there is a change to any file under the Sysvol folder structure, replication is triggered. The dfsrmig command migrates SYSVOL replication from FRS to DFSR. 3. Look at the file replication events of all your domain controllers for replication errors. The original SYSVOL folder is not deleted. However, FRS continues to replicate the original SYSVOL folders and clients continue to use SYSVOL. The only thing that worked for me was when I did an Authoritative FRS restore by changing the BurFlags registry key to D4 and then restarting the File Replication service - that was done on the DC that had replication and SYSLOG issues. This tutorial contains instructions to resolve the following warning event of File Replication Service, after migrating an Active Directory 2003 to AD 2008, 2012 or 2016: "Event 13577, NtFrs: File Replication Service (FRS) is deprecated. For more information, see … DroidFedo. Group Policy template (GPT) is replicated by SYSVOL through FRS, FRS uses state-based replication. Open the Active Directory Domains and Trusts snap-in. This temp SYSVOL folder is not used by any services. Also had failing SYSVOL replication problems. Right-click the domain and choose Raise Domain Functional Level. In order to migrate from FRS to DFSR its must to go from … In this state, DFS Replication will continue its replication and servicing SYSVOL requests. Repeat step 4 to force and verify replication. Since windows server 2003 is going out of support, most people already done or still looking for migrate in to latest versions. To migrate SYSVOL replication from FRS to DFS-R, perform the following steps: 1. That domain controller has now done a D2 of sysvol replication. This causes the Netlogon service to resume sharing out SYSVOL on the domain controller. State 1 c. State 2 d. State 3: b. Consider the following scenario: You want to force the non-authoritative synchronization of SYSVOL on a domain controller. This change occurred between Windows Server 2003 to 2008 and a lot of people missed this step of the upgrade process. Forcing Sysvol replication through NTFRSUTL. Perform the following steps in ADSI Edit to re-enable SYSVOL replication on the authoritative domain controller: Open the properties of the SYSVOL Subscription object of the authoritative domain controller, as described in step 3.ii. How to perform an authoritative synchronization of DFSR-replicated SYSVOL (like "D4" for FRS), In the ADSIEDIT.MSC tool, modify the following DN and two attributes on the domain controller you want to make authoritative (preferrably the PDC Emulator, which is usually the most up to date for SYSVOL contents):CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=FALSEmsDFSR-options=1, Modify the following DN and single attribute on all other domain controllers in that domain:CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=FALSE. Prepared State (1): FRS continues to replicate SYSVOL, The environment prepares a temp SYSVOL folder to be used for DFSR replication. Run the following command from an elevated command prompt on the same server that you set as authoritative:DFSRDIAG POLLAD. I've seen a few options, but I aren't sure what's going to be the best fix. It forces AD to replication its core NCs and policies but does not force an FRS replication. Perform the following steps in ADSI Edit to re-enable SYSVOL replication on the authoritative domain controller: Open the properties of the SYSVOL Subscription object of the authoritative domain controller, as described in step 3.ii. Administrators can use Sonar to watch key statistics on a replica set in order to monitor traffic levels, backlogs, and free space. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. Log Name: File Replication Service Source: NtFrs Date: 7/10/2017 1:30:07 PM Event ID: 13508 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: ..local Description: The File Replication Service is having trouble enabling replication from to for c:\windows\sysvol\domain using the DNS name ..local. This step will enable DFSR replication across the domain controllers and they will start non-authoritatively restoring DFSR Sysvol. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. This behavior is indicative of a replication issue but to be certain, it's necessary to check the file replication logs on all replicating servers. DFS is more efficient than FRS. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. If making any DC authoritative, the PDC Emulator as authoritative is preferable, since its SYSVOL contents are usually most up to date. So migrate your SYSVOL FRS replication to DFSR before introducing new Windows 2016 Domain Controllers to your domain. After hours and hours in which I did not know what to do, I also tried to force frs replication on a static port (even if the servers were on the same subnet without firewall between them) but nothing…. Windows 2000 Server and Windows Server 2003 use the File Replication Service (FRS) to replicate SYSVOL, while Windows Server 2008 uses the newer DFS Replication service in domains that use the Windows Server 2008 domain functional level, and FRS for domains that run older domain functional levels. the source of change can be any domain controller. To solve this problem, we had to manually preform an authoritative synchronization between the domain controllers. DFSR migration only goes as fast as AD replication. At this stage, it is critical to make sure that both Active Directory and FRS-based SYSVOL replication function properly. Windows will delete original SYSVOL folder users by FRS replication and stop the FRS replication. This can especially helps you troubleshooting replication issues. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. The 9 DFS-R States. But Windows server 2008 and later uses Distributed File System (DFS) for the replication. FRS uses state-based replication instead. FRS will continue the replication of its own SYSVOL copy but will not involve with production SYSVOL replication. You can use the new ntfrsutl forcerepl command to enforce replication regardless of the predefined replication schedule. Before upgrading your SYSVOL replication from FRS to DFSR, the Domain Functional Level must be at least what version? Few months ago, client moved replication from FRS to DFSR successfully, but demoting old domain controller made confusion in their environment. Also Read: force sysvol replication on Windows 2008 and windows server 2012. FRS Service is responsible for SYSVOL and DFS Replication. To verify your DCs are using FRS and not DFSR, you can use this command: You will see Event ID 4614 and 4604 in the DFSR event log indicating sysvol replication has been initialized. It was first introduced in Windows 2000 to replace the previous LMREPL technology used in NT3.x and 4 days. For example, if all logon scripts were accidentally deleted and a manual copy of them was placed back on the PDC Emulator role holder, making that server authoritative and all other servers non-authoritative would guarantee success and prevent conflicts. It also assumes you have the ability to restore data that was deleted, overwritten, damaged, etc. On the same DN from Step 1, set msDFSR-Enabled=TRUE. The use of the authoritative flag is only necessary if you need to force synchronization of all DCs. The folder contains such as group policy, users etc of the sysvol folder are replicated to all domain controller in the domain. 12) Run following command to update the DFRS global state, dfsrdiag PollAD. Windows Server 2008: What Global state of FRS to DFSR migration allows for rollback? - The tree level is currently 2003 (all servers are 2008r2) therefore I could upgrade the level which moves it away from FRS and may fix the issue? FRS does not have a schedule associated with it. DFS-R begins to replicate the contents of the SYSVOL_DFSR folders on all domain controllers. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. As soon as there is a change to any file under the Sysvol folder structure, replication is triggered an entire file gets replicated Find answers to Is there any way to force replication of SYSVOL without danger? Replication is used to synchronize the contents of the SYSVOL directory between DCs, and replication is not provided by AD, but by using NtFRS (File Replication Service) or DFS-R service. a. The "File Replication Service (FRS) is deprecated" error appears because, after the introduction of Windows Server 2008, the Domain Controllers uses the newer Distributed File System Replication (DFSR) instead of the File Replication Service (FRS), in order to replicate the logon scripts and the Group Policy object files from the SYSVOL folder, to other domain controllers. Otherwise you will see conflicts on DCs, originating from any DCs where you did not set auth/non-auth and restarted the DFSR service. State 3 – Eliminated . 5 In 2000, Microsoft introduced the File Replication Service (FRS) in Windows Server in order to asynchronously replicate file data. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Bur Flags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. 13) Search for the event 4602 and verify the successful SYSVOL replication. Ensure that the ‘ SysVol ’ registry key is pointing to the ‘SYSVOL_DFSR’ folder location. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. Only FRS is used to replicate SYSVOL. Start the DFSR service set as authoritative: You will see Event ID 4114 in the DFSR event log indicating SYSVOL is no longer being replicated. 12) Run following command to update the DFRS global state, dfsrdiag PollAD. Replication of the old SYSVOL folder by FRS is stopped. Repeat step 4 to force and verify replication. previously if this is a disaster recovery scenario on all DCs in the domain. Start the DFSR service on the other non-authoritative DCs. Selecting a language below will dynamically change the complete page content to that language. Force Active Directory replication throughout the domain and validate its success on all DCs. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. Unlike custom DFSR replicated folders, sysvol replication is intentionally protected from any editing through its management interfaces to prevent accidents. You can restart the FRS service to force the FRS replication To restart the FRS service, launch services.msc from the Run option on the Start Menu And restart the FRS service and you will get the Event ID 13516 on FRS event log this will ensure the FRS status is fine Forcing Sysvol replication through NTFRSUTL If you had more than one affected DC, expand the steps to include ALL of those as well. If setting the authoritative flag on one DC, you must non-authoritatively synchronize all other DCs in the domain. This change occurred between Windows Server 2003 to 2008 and a lot of people missed this step of the upgrade process. SYSVOL Replication Migration Guide: FRS to DFS Replication Important! Run the following command from an elevated command prompt on all non-authoritative DCs (that is, all but the formerly authoritative one): Return the DFSR service to its original Startup Type (Automatic) on all DCs. Step 12. If this event occurred during the migration of SYSVOL from File Replication service (FRS) to DFS Replication, changes will not replicate out until this issue is resolved. The use of the authoritative flag is only necessary if you need to force synchronization of all DCs. In the ADSIEDIT.MSC tool, modify the following DN and two attributes on the domain controller you want to make authoritative (preferably the PDC Emulator, which is usually the most up to date for sysvol replication contents): Modify the following DN and single attribute on all other domain controllers in that domain: Force Active Directory replication throughout the domain and validate its success on all DCs. State 3 – Eliminated. And restart the FRS service and you will get the Event ID 13516 on FRS event log this will ensure the FRS status is fine Forcing Sysvol replication through NTFRSUTL If you want to force sysvol replication between two domain controllers in an active directory then use the below procedure NTFRSUTL FORCEREPL Command-Line Option to Force Replication You can use the new ntfrsutl forcerepl … My issue was sysvol was not replicating on my 2019 domain controllers so not only did I need to be able to force sysvol replication, I needed to get to the root of the issue to figure out why. Since then, Microsoft released the Distributed File System Replication (DFSR) and deprecated FRS. Today we’re going to fix sysvol folders not replicating across domain controllers. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service.You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command … Start the DFSR service on the domain controller that was set as authoritative in Step 2. Failing SYSVOL replication problems may cause Group Policy problems. The specified domain %1 is still using the File Replication Service (FRS) to replicate the SYSVOL share. START (stable state 0) designates the initial point of the migration. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line tool to achieve this. If making any DC authoritative, the PDC Emulator as authoritative is preferable, since its sysvol replication contents are most up to date. Migrating SYSVOL AD Replication from FRS to DFS June 7, 2019 Cyril Kardashevsky Active Directory The SYSVOL folder on any Active Directory domain controller stores Group Policies settings and templates, scripts, and other objects that the AD or GPO administrator placed there. START (stable state 0) designates the initial point of the migration. Windows will delete original SYSVOL folder users by FRS replication and stop the FRS replication. The Sysvol is replicated using the File Replication System (FRS). 1 (prepared) A copy of SYSVOL is created in a folder called SYSVOL_DFSR and is added to a replication set. all but the formerly authoritative one):DFSRDIAG POLLAD. As soon as initial sync is finished, event ID 4604 is logged, signaling SYSVOL has completed initialization. You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. In Windows Server 2003 (and earlier), to replicate SYSVOL folder in the domain the FRS technology was used, but in Windows Server 2008 R2, this replication technology was deprecated and Microsoft recommends to use DFS replication, because FRS is not a reliable file replication technology.. Run the following command from an elevated command prompt on the same servers that you set as non-authoritative:DFSRDIAG POLLAD. Change msDFSR-Enabled to True. The sysvol folder must be located on the NTFS Volume. With the introduction of Windows Server 2016 the old FRS SYSVOL replication is deprecated. The FRS-feature will be removed in nearby future of new Windows 2016 releases. The dfsrmig command migrates SYSVOL replication from FRS to DFSR. If setting the authoritative flag on one DC, you must non-authoritatively synchronizeall other DCs in the domain. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. FRS … d) A dependency is added such that the DFSR service depends on the NTDS service. This means that any server that is part of the replication set can make changes. You want to force the non-authoritative synchronization of sysvol replication on a domain controller (DC). The SYSVOL folder stores the server’s copy of the domain public files. FRS is deprecated. In the ADSIEDIT.MSC tool, modify the following distinguished name (DN) value and attribute on each of the domain controllers (DCs) that you want to make non-authoritative: Force Active Directory replication throughout the domain. Step 13 If you upgraded from Windows 2003 domain, there is a big chance that you are still using FRS (File Replication Service). This article introduces how to force an authoritative and non-authoritative synchronization for DFSR-replicated sysvol replication. To force the SYSVOL to be replicated to the branch location, simply run the following command on DC1, the server which you want to replicate from: ntfrsutl forcerepl DC1.domain.local /r "domain system volume (sysvol share)" /p DC2.domain.local If the command executes correctly you will see the following output: LocalComputerName = DC1.domain.local To be sure, run following command on one of your DCs: dfsrmig /getmigrationstate. Otherwise you will see conflicts on DCs, originating from any DCs where you did not set auth/non-auth and restarted the DFSR service.For example, if all logon scripts were accidentally deleted and a manual copy of them was placed back on the PDC Emulator role holder, making that server authoritative and all other servers non-authoritative would guarantee success and prevent conflicts. Unlike custom DFSR replicated folders, SYSVOL is intentionally protected from any editing through its management interfaces to prevent accidents. 13) Search for the event 4602 and verify the successful SYSVOL replication. At this stage, it is critical to make sure that both Active Directory and FRS-based SYSVOL replication function properly. This behavior is indicative of a replication issue but to be certain, it's necessary to check the file replication logs on all replicating servers. In this state, DFS Replication will continue its replication and servicing SYSVOL requests. Run the following command from an elevated command prompt on the same servers that you set as non-authoritative: You will see Event ID 4114 in the DFSR event log indicating sysvol replication is no longer being replicated. Same information is available for the User Configuration. CERTIFIED EXPERT.

force sysvol replication frs

Presentation. After replication resumes, it will log an event ID 4602 that indicates that DFS Replication initialized the SYSVOL replicated folder and specified it as the primary member. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Bur Flags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. What you need to do SYSVOL is still replicated by FRS for failback. Open server manager and look in event viewer > application and service logs > file replication service. If this event occurred during the migration of SYSVOL from File Replication service (FRS) to DFS Replication, changes will not replicate out until this issue is resolved. But dfsrmig can also give you an overview of your architecture's overall state before you actually start migrating. 3 (eliminated). Replication is multi-master, i.e. To test the former, use the RepAdmin command line utility (with /showrepl /all or /replsum switches). You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line … Start the DFSR service on the other non-authoritative DCs. You want to force the non-authoritative synchronization of sysvol replication on a domain controller (DC). This can cause the SYSVOL folder on this server to become out of sync with other domain controllers. FRS is deprecated. You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. Set the DFS Replication service Startup Type to Manual, and stop the service on all domain controllers in the domain. How to perform a non-authoritative synchronization of DFSR-replicated SYSVOL (like "D2" for FRS), In the ADSIEDIT.MSC tool modify the following distinguished name (DN) value and attribute on each of the domain controllers that you want to make non-authoritative:CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=FALSE. State 0 b. Force Active Directory replication throughout the domain. You will see Event ID 4114 in the DFSR event log indicating SYSVOL is no longer being replicated. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. If only repairing one DC, simply make it non-authoritative and do not touch other servers. That domain controller has now done a D4 of sysvol replication. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line tool to achieve this. That domain controller has now done a “D2” of SYSVOL. 11) Force the AD replication using, repadmin /syncall /AdP. a. Run the dfsrdiag pollad command on the second domain controller to trigger it to complete initial sync (event ID 4614). You will see Event ID 4614 and 4604 in the DFSR event log indicating SYSVOL has been initialized. 14) Start DFS service on all other Domain Controllers. For instance, this command will force push replication of all partitions while ignoring the schedules (this is a rather sledgehammer example): Repadmin /syncall /force /APed Furthermore, DFSR SYSVOL only replicates when AD has an open schedule (DFSR does not know about change notification). Windows Server 2003 b. previously if this is a disaster recovery scenario on all DCs in the domain. If changes occurred on multiple controllers, the last change will take precedence. Force Active Directory replication throughout the domain. But at least I saw that the service responded (although I had already had a confirmation about that with the command NTFRSUTL VERSION). You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. That domain controller has now done a “D4” of SYSVOL. Windows Server 2003 and 2003 R2 uses File Replication Service (FRS) to replicate SYSVOL folder content to other domain controllers. (Choose all that apply.) You move the DCs through these stages or states, by using the DFSMig command. This article is designed with a 2-DC environment in mind, for simplicity of description. If you want to force sysvol replication between two domain controllers in an active directory then use the below procedure. FRS is deprecated. Original KB number:   2218556. To be sure, run following command on one of your DCs: dfsrmig /getmigrationstate . After deep investigation, we found that is problem with DFS replication of SYSVOL folder. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. It also assumes you have the ability to restore data that was deleted, overwritten, damaged, and so on. Force Active Directory replication throughout the domain. NTFRSUTL FORCEREPL Command-Line Option to Force Replication. Once the migration to the ‘ELIMINATED’ state is complete, ensure that the old copy of the ‘SYSVOL’ folder that was being replicated by FRS is deleted. If only repairing one DC, make it non-authoritative and do not touch other servers. Original product version:   Windows Server 2012 R2 The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR. You will see Event ID 4114 in the DFSR event log indicating SYSVOL is no longer being replicated on each of them. Active Directory replication is different from SYSVOL replication using FRS or DFSR, although both use the replication topology and schedule from AD. Force SYSVOL Replication with File Replication Service (FRS) DroidFedo Monday, March 31, 2014. ..... PRIMARY-DC01 passed test FrsEvent Starting test: DFSREvent ..... PRIMARY-DC01 passed test DFSREvent Starting test: SysVolCheck ..... PRIMARY-DC01 passed test SysVolCheck Starting test: KccEvent ..... PRIMARY-DC01 passed test KccEvent Starting test: KnowsOfRoleHolders ..... PRIMARY-DC01 passed test … In this movie we show how to fix SYSVOL replication if it stops working with an Authoritative DFSR Synchronization. You will see Event ID 4114 in the DFSR event log indicating sysvol replication is no longer being replicated on each of them. As an administrator you may make a group policy change on the domain controller running the PDC emulator and you want this change to be replicated out to a branch location immediately. You will see Event ID 4602 in the DFSR event log indicating SYSVOL has been initialized. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe … This is unnecessary in most cases, and it may cause data loss if done incorrectly. This diagram shows the high-level steps which we will go into more detail about. Function Get-ADGPOReplication. A subscription to make the most of your time. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. If you had more than one affected DC, expand the steps to includeALL of those as well. This article is designed with a 2-DC environment in mind, for simplicity of description. Sonar.exe is a graphical tool that allows administrators to monitor key statistics and status about members of a file replication service (FRS) replica set. The specified domain %1 is still using the File Replication Service (FRS) to replicate the SYSVOL share. Modify the following DN and single attribute on all other domain controllers in that domain:CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=TRUE, Run the following command from an elevated command prompt on all non-authoritative DCs (i.e. 2. FRS will continue the replication of its own SYSVOL copy but will not involve with production SYSVOL replication. Open server manager and look in event viewer > application and service logs > file replication service. If you upgraded from Windows 2003 domain, there is a big chance that you are still using FRS (File Replication Service). Find out if your domain SYSVOL replication is run by FRS or DFS-R If ... (Distributed File System Replication). Get-ADGPOReplication is retrieving the GPO version and Sysvol version accross the domain for one or more Group Policy objects. Look at the file replication events of all your domain controllers for replication errors. c) Force Active Directory replication on a domain controller. Therefore, if you want to remove it entirely, you must do so manually. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. 14) Start DFS service on all other Domain Controllers. Windows Server 2008 c. Windows Server 2008 R2 d. Windows Server 2012 R2: b. On the same DN from Step 1, set:msDFSR-Enabled=TRUE. Furthermore, DFSR SYSVOL only replicates when AD has an open schedule (DFSR does not know about change notification). 11) Force the AD replication using, repadmin /syncall /AdP. Thereafter, it sets the ‘ SysvolReady ’ registry key back to ‘TRUE’ (1). Both 2008 and 2012 continued to function with FRS SYSVOL replication, but with 2016 and above, people using FRS will not be able to introduce a new domain controller into the Active Directory environment. To verify your DCs are using FRS and not DFSR, you can use this command: You want to force the non-authoritative synchronization of SYSVOL on a domain controller. 15) Search for the event 4114 to verify SYSVOL replication is disabled. File Replication Service – FRS FRS is a multi-master, multi-threaded replication technology. Run the following command from an elevated command prompt on the same server that you set as authoritative: You will see Event ID 4602 in the DFSR event log indicating sysvol replication has been initialized. The 9 DFS-R States. To improve the performance, scalability and reliability of SYSVOL replication, use DFS Replication (DFS-R) to replicate the SYSVOL folder, which stores Group Policy objects and logon scripts. For instance, this command will force push replication of all partitions while ignoring the schedules (this is a rather sledgehammer example): Repadmin /syncall /force /APed. The DFS Replication service initialized SYSVOL at local path C:\Windows\SYSVOL\domain and is waiting to perform initial replication. To test the former, use the RepAdmin command line utility (with /showrepl /all or /replsum switches). If this event occurred during the migration of SYSVOL from File Replication service (FRS) to DFS Replication, changes will not replicate out until this issue is resolved. The specified domain %1 is still using the File Replication Service (FRS) to replicate the SYSVOL share. 15) Search for the event 4114 to verify SYSVOL replication is disabled. But dfsrmig can also give you an overview of your architecture's overall state before you actually start migrating. Change msDFSR-Enabled to True. The process, detailed in KB article 2218556 "How to force an authoritative and non-authoritative synchronization for DFSR-replicated SYSVOL (like "D4/D2" for FRS)," reinitializes DFS Replication if SYSVOL is not shared on domain controllers. This means that as soon as there is a change to any file under the Sysvol folder structure, replication is triggered. The dfsrmig command migrates SYSVOL replication from FRS to DFSR. 3. Look at the file replication events of all your domain controllers for replication errors. The original SYSVOL folder is not deleted. However, FRS continues to replicate the original SYSVOL folders and clients continue to use SYSVOL. The only thing that worked for me was when I did an Authoritative FRS restore by changing the BurFlags registry key to D4 and then restarting the File Replication service - that was done on the DC that had replication and SYSLOG issues. This tutorial contains instructions to resolve the following warning event of File Replication Service, after migrating an Active Directory 2003 to AD 2008, 2012 or 2016: "Event 13577, NtFrs: File Replication Service (FRS) is deprecated. For more information, see … DroidFedo. Group Policy template (GPT) is replicated by SYSVOL through FRS, FRS uses state-based replication. Open the Active Directory Domains and Trusts snap-in. This temp SYSVOL folder is not used by any services. Also had failing SYSVOL replication problems. Right-click the domain and choose Raise Domain Functional Level. In order to migrate from FRS to DFSR its must to go from … In this state, DFS Replication will continue its replication and servicing SYSVOL requests. Repeat step 4 to force and verify replication. Since windows server 2003 is going out of support, most people already done or still looking for migrate in to latest versions. To migrate SYSVOL replication from FRS to DFS-R, perform the following steps: 1. That domain controller has now done a D2 of sysvol replication. This causes the Netlogon service to resume sharing out SYSVOL on the domain controller. State 1 c. State 2 d. State 3: b. Consider the following scenario: You want to force the non-authoritative synchronization of SYSVOL on a domain controller. This change occurred between Windows Server 2003 to 2008 and a lot of people missed this step of the upgrade process. Forcing Sysvol replication through NTFRSUTL. Perform the following steps in ADSI Edit to re-enable SYSVOL replication on the authoritative domain controller: Open the properties of the SYSVOL Subscription object of the authoritative domain controller, as described in step 3.ii. How to perform an authoritative synchronization of DFSR-replicated SYSVOL (like "D4" for FRS), In the ADSIEDIT.MSC tool, modify the following DN and two attributes on the domain controller you want to make authoritative (preferrably the PDC Emulator, which is usually the most up to date for SYSVOL contents):CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=FALSEmsDFSR-options=1, Modify the following DN and single attribute on all other domain controllers in that domain:CN=SYSVOL Subscription,CN=Domain System Volume,CN=DFSR-LocalSettings,CN=,OU=Domain Controllers,DC=msDFSR-Enabled=FALSE. Prepared State (1): FRS continues to replicate SYSVOL, The environment prepares a temp SYSVOL folder to be used for DFSR replication. Run the following command from an elevated command prompt on the same server that you set as authoritative:DFSRDIAG POLLAD. I've seen a few options, but I aren't sure what's going to be the best fix. It forces AD to replication its core NCs and policies but does not force an FRS replication. Perform the following steps in ADSI Edit to re-enable SYSVOL replication on the authoritative domain controller: Open the properties of the SYSVOL Subscription object of the authoritative domain controller, as described in step 3.ii. Administrators can use Sonar to watch key statistics on a replica set in order to monitor traffic levels, backlogs, and free space. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. Log Name: File Replication Service Source: NtFrs Date: 7/10/2017 1:30:07 PM Event ID: 13508 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: ..local Description: The File Replication Service is having trouble enabling replication from to for c:\windows\sysvol\domain using the DNS name ..local. This step will enable DFSR replication across the domain controllers and they will start non-authoritatively restoring DFSR Sysvol. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. This behavior is indicative of a replication issue but to be certain, it's necessary to check the file replication logs on all replicating servers. DFS is more efficient than FRS. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. If making any DC authoritative, the PDC Emulator as authoritative is preferable, since its SYSVOL contents are usually most up to date. So migrate your SYSVOL FRS replication to DFSR before introducing new Windows 2016 Domain Controllers to your domain. After hours and hours in which I did not know what to do, I also tried to force frs replication on a static port (even if the servers were on the same subnet without firewall between them) but nothing…. Windows 2000 Server and Windows Server 2003 use the File Replication Service (FRS) to replicate SYSVOL, while Windows Server 2008 uses the newer DFS Replication service in domains that use the Windows Server 2008 domain functional level, and FRS for domains that run older domain functional levels. the source of change can be any domain controller. To solve this problem, we had to manually preform an authoritative synchronization between the domain controllers. DFSR migration only goes as fast as AD replication. At this stage, it is critical to make sure that both Active Directory and FRS-based SYSVOL replication function properly. Windows will delete original SYSVOL folder users by FRS replication and stop the FRS replication. This can especially helps you troubleshooting replication issues. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. The 9 DFS-R States. But Windows server 2008 and later uses Distributed File System (DFS) for the replication. FRS uses state-based replication instead. FRS will continue the replication of its own SYSVOL copy but will not involve with production SYSVOL replication. You can use the new ntfrsutl forcerepl command to enforce replication regardless of the predefined replication schedule. Before upgrading your SYSVOL replication from FRS to DFSR, the Domain Functional Level must be at least what version? Few months ago, client moved replication from FRS to DFSR successfully, but demoting old domain controller made confusion in their environment. Also Read: force sysvol replication on Windows 2008 and windows server 2012. FRS Service is responsible for SYSVOL and DFS Replication. To verify your DCs are using FRS and not DFSR, you can use this command: You will see Event ID 4614 and 4604 in the DFSR event log indicating sysvol replication has been initialized. It was first introduced in Windows 2000 to replace the previous LMREPL technology used in NT3.x and 4 days. For example, if all logon scripts were accidentally deleted and a manual copy of them was placed back on the PDC Emulator role holder, making that server authoritative and all other servers non-authoritative would guarantee success and prevent conflicts. It also assumes you have the ability to restore data that was deleted, overwritten, damaged, etc. On the same DN from Step 1, set msDFSR-Enabled=TRUE. The use of the authoritative flag is only necessary if you need to force synchronization of all DCs. The folder contains such as group policy, users etc of the sysvol folder are replicated to all domain controller in the domain. 12) Run following command to update the DFRS global state, dfsrdiag PollAD. Windows Server 2008: What Global state of FRS to DFSR migration allows for rollback? - The tree level is currently 2003 (all servers are 2008r2) therefore I could upgrade the level which moves it away from FRS and may fix the issue? FRS does not have a schedule associated with it. DFS-R begins to replicate the contents of the SYSVOL_DFSR folders on all domain controllers. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. As soon as there is a change to any file under the Sysvol folder structure, replication is triggered an entire file gets replicated Find answers to Is there any way to force replication of SYSVOL without danger? Replication is used to synchronize the contents of the SYSVOL directory between DCs, and replication is not provided by AD, but by using NtFRS (File Replication Service) or DFS-R service. a. The "File Replication Service (FRS) is deprecated" error appears because, after the introduction of Windows Server 2008, the Domain Controllers uses the newer Distributed File System Replication (DFSR) instead of the File Replication Service (FRS), in order to replicate the logon scripts and the Group Policy object files from the SYSVOL folder, to other domain controllers. Otherwise you will see conflicts on DCs, originating from any DCs where you did not set auth/non-auth and restarted the DFSR service. State 3 – Eliminated . 5 In 2000, Microsoft introduced the File Replication Service (FRS) in Windows Server in order to asynchronously replicate file data. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Bur Flags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. 13) Search for the event 4602 and verify the successful SYSVOL replication. Ensure that the ‘ SysVol ’ registry key is pointing to the ‘SYSVOL_DFSR’ folder location. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. Only FRS is used to replicate SYSVOL. Start the DFSR service set as authoritative: You will see Event ID 4114 in the DFSR event log indicating SYSVOL is no longer being replicated. 12) Run following command to update the DFRS global state, dfsrdiag PollAD. Replication of the old SYSVOL folder by FRS is stopped. Repeat step 4 to force and verify replication. previously if this is a disaster recovery scenario on all DCs in the domain. Start the DFSR service on the other non-authoritative DCs. Selecting a language below will dynamically change the complete page content to that language. Force Active Directory replication throughout the domain and validate its success on all DCs. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. Unlike custom DFSR replicated folders, sysvol replication is intentionally protected from any editing through its management interfaces to prevent accidents. You can restart the FRS service to force the FRS replication To restart the FRS service, launch services.msc from the Run option on the Start Menu And restart the FRS service and you will get the Event ID 13516 on FRS event log this will ensure the FRS status is fine Forcing Sysvol replication through NTFRSUTL If you had more than one affected DC, expand the steps to include ALL of those as well. If setting the authoritative flag on one DC, you must non-authoritatively synchronize all other DCs in the domain. This change occurred between Windows Server 2003 to 2008 and a lot of people missed this step of the upgrade process. SYSVOL Replication Migration Guide: FRS to DFS Replication Important! Run the following command from an elevated command prompt on all non-authoritative DCs (that is, all but the formerly authoritative one): Return the DFSR service to its original Startup Type (Automatic) on all DCs. Step 12. If this event occurred during the migration of SYSVOL from File Replication service (FRS) to DFS Replication, changes will not replicate out until this issue is resolved. The use of the authoritative flag is only necessary if you need to force synchronization of all DCs. In the ADSIEDIT.MSC tool, modify the following DN and two attributes on the domain controller you want to make authoritative (preferably the PDC Emulator, which is usually the most up to date for sysvol replication contents): Modify the following DN and single attribute on all other domain controllers in that domain: Force Active Directory replication throughout the domain and validate its success on all DCs. State 3 – Eliminated. And restart the FRS service and you will get the Event ID 13516 on FRS event log this will ensure the FRS status is fine Forcing Sysvol replication through NTFRSUTL If you want to force sysvol replication between two domain controllers in an active directory then use the below procedure NTFRSUTL FORCEREPL Command-Line Option to Force Replication You can use the new ntfrsutl forcerepl … My issue was sysvol was not replicating on my 2019 domain controllers so not only did I need to be able to force sysvol replication, I needed to get to the root of the issue to figure out why. Since then, Microsoft released the Distributed File System Replication (DFSR) and deprecated FRS. Today we’re going to fix sysvol folders not replicating across domain controllers. In the File Replication Service (FRS), this was controlled through the D2 and D4 data values for the Burflags registry values, but these values do not exist for the Distributed File System Replication (DFSR) service.You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command … Start the DFSR service on the domain controller that was set as authoritative in Step 2. Failing SYSVOL replication problems may cause Group Policy problems. The specified domain %1 is still using the File Replication Service (FRS) to replicate the SYSVOL share. START (stable state 0) designates the initial point of the migration. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line tool to achieve this. If making any DC authoritative, the PDC Emulator as authoritative is preferable, since its sysvol replication contents are most up to date. Migrating SYSVOL AD Replication from FRS to DFS June 7, 2019 Cyril Kardashevsky Active Directory The SYSVOL folder on any Active Directory domain controller stores Group Policies settings and templates, scripts, and other objects that the AD or GPO administrator placed there. START (stable state 0) designates the initial point of the migration. Windows will delete original SYSVOL folder users by FRS replication and stop the FRS replication. The Sysvol is replicated using the File Replication System (FRS). 1 (prepared) A copy of SYSVOL is created in a folder called SYSVOL_DFSR and is added to a replication set. all but the formerly authoritative one):DFSRDIAG POLLAD. As soon as initial sync is finished, event ID 4604 is logged, signaling SYSVOL has completed initialization. You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. In Windows Server 2003 (and earlier), to replicate SYSVOL folder in the domain the FRS technology was used, but in Windows Server 2008 R2, this replication technology was deprecated and Microsoft recommends to use DFS replication, because FRS is not a reliable file replication technology.. Run the following command from an elevated command prompt on the same servers that you set as non-authoritative:DFSRDIAG POLLAD. Change msDFSR-Enabled to True. The sysvol folder must be located on the NTFS Volume. With the introduction of Windows Server 2016 the old FRS SYSVOL replication is deprecated. The FRS-feature will be removed in nearby future of new Windows 2016 releases. The dfsrmig command migrates SYSVOL replication from FRS to DFSR. If setting the authoritative flag on one DC, you must non-authoritatively synchronizeall other DCs in the domain. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. FRS … d) A dependency is added such that the DFSR service depends on the NTDS service. This means that any server that is part of the replication set can make changes. You want to force the non-authoritative synchronization of sysvol replication on a domain controller (DC). The SYSVOL folder stores the server’s copy of the domain public files. FRS is deprecated. In the ADSIEDIT.MSC tool, modify the following distinguished name (DN) value and attribute on each of the domain controllers (DCs) that you want to make non-authoritative: Force Active Directory replication throughout the domain. Step 13 If you upgraded from Windows 2003 domain, there is a big chance that you are still using FRS (File Replication Service). This article introduces how to force an authoritative and non-authoritative synchronization for DFSR-replicated sysvol replication. To force the SYSVOL to be replicated to the branch location, simply run the following command on DC1, the server which you want to replicate from: ntfrsutl forcerepl DC1.domain.local /r "domain system volume (sysvol share)" /p DC2.domain.local If the command executes correctly you will see the following output: LocalComputerName = DC1.domain.local To be sure, run following command on one of your DCs: dfsrmig /getmigrationstate. Otherwise you will see conflicts on DCs, originating from any DCs where you did not set auth/non-auth and restarted the DFSR service.For example, if all logon scripts were accidentally deleted and a manual copy of them was placed back on the PDC Emulator role holder, making that server authoritative and all other servers non-authoritative would guarantee success and prevent conflicts. Unlike custom DFSR replicated folders, SYSVOL is intentionally protected from any editing through its management interfaces to prevent accidents. 13) Search for the event 4602 and verify the successful SYSVOL replication. At this stage, it is critical to make sure that both Active Directory and FRS-based SYSVOL replication function properly. This behavior is indicative of a replication issue but to be certain, it's necessary to check the file replication logs on all replicating servers. In this state, DFS Replication will continue its replication and servicing SYSVOL requests. Run the following command from an elevated command prompt on the same servers that you set as non-authoritative: You will see Event ID 4114 in the DFSR event log indicating sysvol replication is no longer being replicated. Same information is available for the User Configuration. CERTIFIED EXPERT.
