FRS/RPC not working on new DC - Please Help!
I'm hoping someone can help me. I'm having issues getting a 3rd DC up and running.
We have 2 DCs that appear to be happily replicating AD and DNS (Active Directory Integrated) and the SYSVOL folders without a problem.
Am trying to add a 3rd DC (after we properly demoted an old one a while back). AD replicates fine, DNS (ADI) replicates fine, but SYSVOL is not replicating or even sharing on the new DC.
Getting an FRS Event ID 13508 in Event Viewer which basically says it can't talk to either of the other servers to do FRS. It is not followed by a 13509 to say it has made a connection.
According to MS the root cause of a 15308 is 'FRS was unable to create an RPC connection to a replication partner' - it's solution is to 'troubleshoot'... much help!
In AD Sites & Directories the original two DCs have both made automatic connections to the new DC but the new DC hasn't made any to the old DCs. I've tried creating them manually and forcing replication but this hasn't worked.
I've tried setting the BurFlags in regedit so that one of the old DCs (set to D4) was the Authoritative restore and the other DCs were non-authoratitive... didn't work - just rebuilt a new Netlogon folder and Policies folder.... meaning no scripts or policies worked until I manually copied them from the old folder to the new folder on of the original DCs - which then replicated to the other orginal DC without a problem.... but not the new DC.
Tried to demote the new DC back to a Member server but it won't demote as its says RPC is unavailable.... which backs up that there is a problem with RPC on the new DC .. but where do I go from here?
I'm stuck and need help!
