My setup is as follows:
Site A has one Windows 2012 Domain Controller called AVHDCADC01
Site B has one Windows 2012 Domain Controller called AVHDCBDC01
AVHDCADC01 has all FSMO Roles, is a Domain Controller and is working correctly.
AVHDCBDC01 has been turned off for a significant period of time, and now it has been turned back on, AD is not working - the last successful replication occurred in February, so I'm imagining some kind of Tombstoning has occurred, but I'm really not sure about this so I was hoping someone could point me in the right direction.
I am confident the IP configurations are correct, running the command "repadmin /showrepl * /errorsonly" on AVHDCBDC01 gives the following results:
C:\Users\Administrator.AVH>repadmin /showrepl * /errorsonly
Repadmin: running command /showrepl against full DC AVHDCADC01.avh.local
LDAP error 82 (Local Error) Win32 Err 8341.
Repadmin: running command /showrepl against full DC AVHDCBDC01.avh.local

I have found the following post, http://technet.microsoft.com/en-us/library/replication-error-2146893022-the-target-principal-name-is-incorrect(v=ws.10).aspx
But I am unsure if this is relevant to what I'm trying to solve, and if it is, which commands I should actually run!
I really don't want to have to rebuild the domain controller so this is my last shot before I resort to that.
Would greatly appreciate any help.
