I have 2 2012 servers. I found out there's no share of neither SYSVOL nor NETLOGON on the BDC.
I'm getting many 5002:
The DFS Replication service encountered an error communicating with partner QA-DC for replication group Domain System Volume.
The DFS replication service initilizaed SYSVOL at local path c:\windows\sysvol\domain and is waiting to perform initial replication
I already tried non-authoritive restore on the BDC and authoritive restore on the PDC according to this guide: http://support.microsoft.com/kb/2218556
I'm afraid that didnt help.
I found something strange... Looking at the debug log it looks like dev-dc which is my secondary DC, does not even try to communicate with QA-DC which is the PDC. The logs do show this problematic(?) line:
"Cluster Service is not installed or configured. Skipping VCO Polling".
One more thing I found out is when looking at "DFS Management" snapping I discovered that QA-DC's membership in the "Domain System Volume" is somehow disabled...
