No permissions on DC after promotion

A Windows 2012 R2 was promoted as a DC in an existing domain.  The domain is running functional level domain/forest of 2003.  There are other 2012 R2 machines already promoted and behaving.

After the promotion we can login with domain credentials but we can't run anything as Administrator - like Server Manager.  A popup indicates we may not have sufficient rights.  If I drill to c:\windows\system32\servermanager.exe and try to RunAs and enter domain credentials I get an access denied.

At this point I'd like to demote it as a DC, but can't open powershell or server manager as administrator.

Any ideas as to how I might troubleshoot this.  As a 2nd option is there a way to remotely demote the DC.

I assume you have some GPO, which is blocking access to your new DC's. Check what all GPO's are applied on DC's.

If you want to demote, you can delete them from AD and perform metadata cleanup and then promote again. However, until you find the cause, i don't see any reason of demoting them.

There's only one DC I'm having a issue with.  We had promoted one the other day that appears to be working normally.  All the DC's are in the default Domain Controllers OU.  From what I can tell replication is occurring.

I've attached dcdiag.txt after running dcdiag.exe on the server.  Some of the errors may be because I can't open anything as Administrator

It is still replicating. DC promotion is not completed. Leave server for a day. Then check again.

I finally had to delete the dc out of AD and perform a meta-data cleanup.  Removed the server from the domain.  Reset all the DNS settings.  After that I successfully joined server to domain and promoted as a DC.
