For mission-critical data replication, customers require additional functionality from the service as follows: Many of these address basic visibility and control issues inherent in the service. The issue continues even on DCs in the same AD site as the PDCE, where AD replication occurs every 15 seconds and where you have run DFSRDIAG.EXE POLLAD on all the DCs. Allow AD and SYSVOL replication to converge on all DCs. Do a final copy of changed files to the new share. Running the /GETMIGRATIONSTATE reporting command shows: DFSRMIG.EXE /GETMIGRATIONSTATE Domain Controller (Local Migration State) - DC Type Guidance for troubleshooting DFS Namespace - Windows Server It isn't normal for them to remain in that state even after AD replication has reached those DCs and 15 minutes has passed for DFSR AD Polling. The sysvol may not be shared on any of the DCs. Hi Team, You MUST migrate the specified domain to use DFS Replication using the DFSRMIG command before continuing. I had to remove the machine from the domain Before doing that . To fix this issue, force AD replication between the local AD site and the remote AD site and on the DFSR servers, run, An improperly sized / low staging area causes a replication, Avoid replicating bulky files that keep open, dfsrdiag backlog /rgname: /rfname: /smem: /rmem: [/v], dfsrdiag backlog /rgname: /rfname: /smem: /rmem: [/v], We can see now the DFSR folder, this folder contains the DFSR database along with checkpoint files, jrs files, and staged files in chunks. DFS related Registry keys that have been introduced with hotfixes or security updates: . When initial sync (one-way sync) triggers, we should get event ID 4102 under DFSR logs. In this case, data replication gets stopped back and forth on the affected member.
