I have two Windows Server 2008R2 DCs in production environment that are not replicating properly. Users cannot access some network resources including Exchage 2010 server. Digging into the problem I found that the DCs are not replicating the SYSVOL correctly (EventID:6804 "The DFS Replication service has detected that no connections are configured for replication group Domain System Volume. No data is being replicated for this replication group."). Looking in DFS Management at the Sysvol on main DC shows only itself in replication group, looking on the secondary dc, shows both DCs correctly. Looking in ADSIEdit, I see that the msDFSR-Member AD object is not present on main DC. Can I simply recreate the object to solve this issue, or what should I do?
