You will see Event ID 4614 and 4604 in the DFSR event log indicating sysvol replication has been initialized. Look at the file replication events of all your domain controllers for replication errors. State 0 b. What you need to do You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. If you upgraded from Windows 2003 domain, there is a big chance that you are still using FRS (File Replication Service). I've seen a few options, but I aren't sure what's going to be the best fix. 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. If only repairing one DC, make it non-authoritative and do not touch other servers. If you had more than one affected DC, expand the steps to includeALL of those as well. This change occurred between Windows Server 2003 to 2008 and a lot of people missed this step of the upgrade process. Repeat step 4 to force and verify replication. 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. Repeat step 4 to force and verify replication. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. A subscription to make the most of your time. Open server manager and look in event viewer > application and service logs > file replication service. If you want to force sysvol replication between two domain controllers in an active directory then use the below procedure. Replication is multi-master, i.e. 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. Open server manager and look in event viewer > application and service logs > file replication service. If changes occurred on multiple controllers, the last change will take precedence. Replication of the old SYSVOL folder by FRS is stopped. For more information, see … - 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? The folder contains such as group policy, users etc of the sysvol folder are replicated to all domain controller in the domain. 3 (eliminated). State 3 – Eliminated . 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. a. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. Change msDFSR-Enabled to True. You want to force the non-authoritative synchronization of sysvol replication on a domain controller (DC). Active Directory replication is different from SYSVOL replication using FRS or DFSR, although both use the replication topology and schedule from AD. You can use the new ntfrsutl forcerepl command to enforce replication regardless of the predefined replication schedule. 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. Force SYSVOL Replication with File Replication Service (FRS) DroidFedo Monday, March 31, 2014. Only FRS is used to replicate SYSVOL. The dfsrmig command migrates SYSVOL replication from FRS to DFSR. 1 (prepared) A copy of SYSVOL is created in a folder called SYSVOL_DFSR and is added to a replication set. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. Group Policy template (GPT) is replicated by SYSVOL through FRS, FRS uses state-based replication. Therefore, if you want to remove it entirely, you must do so manually. Run the dfsrdiag pollad command on the second domain controller to trigger it to complete initial sync (event ID 4614). Unfortunately, that does not force an FRS replication cycle. 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…. The use of the authoritative flag is only necessary if you need to force synchronization of all DCs. Unlike custom DFSR replicated folders, sysvol replication is intentionally protected from any editing through its management interfaces to prevent accidents. On the same DN from Step 1, set:msDFSR-Enabled=TRUE. Run the following command from an elevated command prompt on the same server that you set as authoritative:DFSRDIAG POLLAD. For now (23-06-2017) this means the FRS feature is still there, but you will receive warnings while promoting a Windows 2016 DC and still using FRS. ..... 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 … Set the DFS Replication service Startup Type to Manual, and stop the service on all domain controllers in the domain. That domain controller has now done a D2 of sysvol replication. previously if this is a disaster recovery scenario on all DCs in the domain. 12) Run following command to update the DFRS global state, dfsrdiag PollAD. 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. 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. Find answers to Is there any way to force replication of SYSVOL without danger? The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. 13) Search for the event 4602 and verify the successful SYSVOL replication. Find out if your domain SYSVOL replication is run by FRS or DFS-R If ... (Distributed File System Replication). As soon as there is a change to any file under the Sysvol folder structure, replication is triggered an entire file gets replicated 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. However, FRS continues to replicate the original SYSVOL folders and clients continue to use SYSVOL. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. 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. 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. 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. Force Active Directory replication throughout the domain. Get-ADGPOReplication is retrieving the GPO version and Sysvol version accross the domain for one or more Group Policy objects. The sysvol folder must be located on the NTFS Volume. CERTIFIED EXPERT. File Replication Service – FRS FRS is a multi-master, multi-threaded replication technology. 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. 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. This can especially helps you troubleshooting replication issues. The 9 DFS-R States. If you had more than one affected DC, expand the steps to include ALL of those as well. Few months ago, client moved replication from FRS to DFSR successfully, but demoting old domain controller made confusion in their environment. DFSR migration only goes as fast as AD replication. Start the DFSR service on the other non-authoritative DCs. 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. You cannot use the DFS Management snap-in (Dfsmgmt.msc) or the Dfsradmin.exe command-line tool to achieve this. To be sure, run following command on one of your DCs: dfsrmig /getmigrationstate. The use of the authoritative flag is only necessary if you need to force synchronization of all DCs. You want to force the non-authoritative synchronization of SYSVOL on a domain controller. Prepared State (1): FRS continues to replicate SYSVOL, The environment prepares a temp SYSVOL folder to be used for DFSR replication. 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. 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. On the same DN from Step 1, set msDFSR-Enabled=TRUE. 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. In this movie we show how to fix SYSVOL replication if it stops working with an Authoritative DFSR Synchronization. The DFS Replication service initialized SYSVOL at local path C:\Windows\SYSVOL\domain and is waiting to perform initial replication. 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 … Original KB number:   2218556. DFS is more efficient than FRS. In order to migrate from FRS to DFSR its must to go from … 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.
