I have a client that has some major replication issues. Turns out one of their DCs failed and they never demoted it. When they replaced it, they named the new DC the same name as the failed DC. In turn I am seeing errors where it is trying to replicate to the old DC. Obviously the errors look like it is trying to replicate to itself (same name). I am aware of scripts that will remove the old DC from the environment but my problem comes with I'm not sure it will remove the correct one.
Just want to see what you all think of my plan of attack.
1) I am going to demote the current DC (transfer roles away and what have you first of course!)
2) Rename the server
3) Use a tool to remove any remains of either DC
4) Promote the server under its new name in the domain.
To be honest I've never come across someone naming a DC the same as an old one. Any gotchas I should look out for? Am I out in left field with the solution?
Thanks for the input!
