Errors After Renaming Domain Controller to Old Domain Controller Name
Posted on 2012-04-13
I am replacing an old 2003 DC with new hardware with 2008R2 DC, and keeping the old name for file share, file redirection purposes. I have successfully joined the 2008DC to the domain, let it replicate, and demoted the 2003DC.
I renamed the old DC to 2003DCOLD and changed IP.
I renamed the new 2008 DC to 2008DC changed IP to that of the old one.
I restarted both servers.
Now, I see that Active Directory SItes and Services shows both instances of the 2008 DC, both as the temporary name, and the old name. And it's trying to replicate from the temporary name, which no longer exists and is now the new name.
Do I delete the temporary name from sites and services?
I'm also getting errors in the event log:
such as in the FIle Server Log - Error DFSR - The DFS Namespace service could not initialize the trusted domain information on this domain controller, but it will periodically retry the operation. The return code is in the record data.
And System - GroupPolicy - 1055 - The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).
