The task can be easy or complicated based on the active directory health / issues. 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. Even after forcing replication, if the DFSR initial sync sill did not start, then there must be some issue with AD replication and you need to troubleshoot further.

Distributed File System Replication (DFS-R or DFSR) is a native replication service in Windows that organizations can use to replicate folders across file servers in distributed locations. 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. If DFSR data being replicated remains open either on the source or destination, then the file system puts exclusive locks on data being replicated, in that case, data is prevented from staging to thefinal destination (replicated directory) or vice versa.

Validate that some or all of the DCs have reached the Prepared state and are ready to redirect. The service has automatically initiated a recovery process. The ideal solution to this case is to keep the staging area to be as equal to the data size being replicated, since this is not possible, we should increase the staging area to be as maximum as possible / affordable by comparing the size of data to be replicated and available disk space on the primary / secondary or both servers based on event log occurrence. On the affected DC, run: Validate that the DC now shares SYSVOL and NETLOGON, and replicates SYSVOL inbound.

DFS recovery is turned on and the backlog is growing since no replication is currently occurring. The resolution for each problem is available on the internet generally in standalone posts. The majority of DFSR issues arise because of active directory replication issues, inadequate staging quota, sharing violations of open files, a corrupted DFSR database, unexpected dirty database shutdowns, conflicting data modifications, and accidental data deletion. But it may be possible that command fails to remove the folder and its contents, at least the command fails on my lab servers.
