In state-based replication, each server in the multi-master system applies updates to its replica as they arrive, without exchanging log files (it instead uses version vectors to maintain "up-to-dateness" information). On the affected DC, run: Validate that the DC now shares SYSVOL and NETLOGON, and replicates SYSVOL inbound. Enable it in DFS.6. File sharing designed for small teams who don't require the fastest transfer speed, more than 2 servers or central management. I added a "LocalAdmin" -- but didn't set the type to admin. I decided to let MS install the 22H2 build. The purged file now needs to be replicated from the source server again. Get-DfsrState: This command shows you current replication state of DFS-R in regard to its DFS replication group partners. Examining the DFS Replication event sign in the Primary Domain Controller (PDC) Emulator shows: Examining the DFSR Debug sign in the PDCE shows: Scenario 2: A domain already replicates SYSVOL using DFSR. Option two is to use the Dfsrdiag.exe tool that provides DFSR status. The service has automatically initiated a recovery process. I stopped using DFSR to migrate file shares. Set up DFS namespace and assign the old share and new share. The source server replicates the file to the destination server staging, however, the file get purged as part of staging cleanup process before the file can be moved into the Replicated Folder.

Replication is very slow with latency or almost getting stopped and the backlog is noticeably increased from the source to the destination server. The DFS-R service is widely used and suffers from well-known deficiencies, foremost among these being a general lack of visibility into the replication process. Thanks for contributing an answer to Server Fault! Promote one or more Windows Server 2008 R2, Windows Server 2012 R2, or Windows Server 2016 domain controllers in that domain. Therefore, the SYSVOL and NETLOGON folders for the domain controllers are no longer shared, and the domain controllers stop responding to location questions from clients in the domain. When initial sync (one-way sync) triggers, we should get event ID 4102 under DFSR logs. Instead, when the new DFSR behaviour is triggered, event ID 2213 is logged in the DFSR log. Demote all Windows Server 2019-based domain controllers to member servers. When relying on DFS-R and its algorithms for mission-critical replication, this lack of visibility can be extremely frustrating for administrators tasked with keeping these critical services operational and users happy. All DCs are automatically members of the built-in Administrators group. For more information, see Troubleshooting Active Directory Replication Problems.
