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. Unfortunately, the prospects of Microsoft fixing these deficiencies is not likely. If recovery is still at the first stage, you will see many entries that say
