I have multiple Windows 2008 R2 and 2012 Servers connected across WAN links that are members of a DFS-R group. Recently, one of my 2012 Servers has stopped replicating files with the other members. Both old and new files are not replicated to and from when created on either side.
I've checked the DFS Replication event log on the affected server and found the following event:
The DFS Replication service stopped replication on volume C:. This occurs when a DFSR JET database is not shut down cleanly and Auto Recovery is disabled. To resolve this issue, back up the files in the affected replicated folders, and then use the ResumeReplication WMI method to resume replication.
1. Back up the files in all replicated folders on the volume. Failure to do so may result in data loss due to unexpected conflict resolution during the recovery of the replicated folders.
2. To resume the replication for this volume, use the WMI method ResumeReplication of the DfsrVolumeConfig class. For example, from an elevated command prompt, type the following command:
wmic /namespace:\\root\microsoftdfs path dfsrVolumeConfig where volumeGuid="B12C7BBF-7B46-11E2-93E7-806E6F6E6963" call ResumeReplication
