Hello Isabella Brown,
Thank you for posting question on Microsoft Windows Forum!
Well! When a Domain Controller experiences a dirty shutdown, the DFS Replication service intentionally pauses replication on the affected volume and logs Event ID 2213. This is a built-in protection mechanism to prevent potential Jet database corruption from propagating across your domain.
Before instructing DFSR to resume, it is recommended to verify the following points to make sure that the underlying infrastructure is healthy and secure a rollback point.
- Since SYSVOL replication relies heavily on a healthy AD topology. Run repadmin /showrepl and repadmin /replsummary in an elevated command prompt. Ensure there are no inbound or outbound AD replication failures.
- Backup the Local SYSVOL Folder by creating a flat-file copy of the C:\Windows\SYSVOL directory on the affected DCs to a temporary location. If the recovery process encounters fatal database corruption and forces a non-authoritative synchronization that drops files into the DfsrPrivate\ConflictAndDeleted folder, you will have a pristine backup of your GPOs and logon scripts.
- To identify the Volume GUID by opening the DFS Replication event log on the affected DC and locate Event ID 2213. The description will explicitly list the VolumeGuid. Copy this exact string.
Once the pre-checks are clear, you can instruct the DFSR service to perform a consistency check, rebuild the database if necessary, and resume replication. Please note: It is very important not to restart the DFSR service or the server during this phase. DFSR is verifying the database against the file system, which takes time depending on the size of your SYSVOL directory. it is advised to monitor consistently the DFS Replication Event Log for the Event ID 2212 which indicates that the DFSR service has started the database recovery/rebuild process, event ID 2214 which confirms the database recovery has completed successfully and event ID 4602 (or 4614) which confirms the SYSVOL replicated folder has successfully initialized and is now actively participating in replication.
Please note: If several DCs received 2213 from the same power outage, treat each affected volume/DC independently. Don't assume that because one DC successfully resumes, every other DC is safe to resume without checking its own 2213, SYSVOL state, and DFSR errors.
