We must copy the replicated folder before resuming the replicated folder to avoid any data loss that may occur and then run the command to resume replication as mentioned above. The server being promoted does not support FRS and cannot be promoted as a replica into the specified domain. This is an unsupported configuration. Now make the DFSR service mode to automatic and start the DFSR service. Then, look for the DFS referral. 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. In any case it will be the highest number and the only file not GZipped. Key: HKLM\System\CurrentControlSet\Services\DFSR\Parameters, With this registry set, there is no auto recovery for DFSR dirty shutdown databases and they must resume replication manually.
