Errors After Renaming Domain Controller to Old Domain Controller Name

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).

How did you rename the DC?

Did you go through this process? http://www.petri.co.il/rename-windows-server-2008-domain-controllers.htm

No I did it through system properties and changed name and rebooted - guess that was the wrong way - what are my next steps to get this resolved?

Also, when I ping domain.net from the new domain controller, it has the domain.net associated with the old temporary IP address.  How do I change it so it associates domain.net with the current ip address?

I already demoted the old domain controller that has the same name.

Should I rename this domain controller to a different new name using the instructions your provided, let the replication finish. Then rename it back to the old name with your instructions?

I believe the step I missed, was deleting the 2003DC from Active Directory after demoting it and changing the name, then when I went to rename the 2008DC to the old 2003DC name, it caused a conflict. For when I look at the name properties in Active Directory of the name, it shows it is a 2003 server, when it actually should show a 2008.

When I run the command it says:

Unable to add 2008DC.domain.net
as an alternate name for the computer.
The error is:

The network path was not found.

The command failed to complete successfully.

Right since you have already renamed the DC. Now try renaming back the same way you did it to the name it was. Try going through the steps to rename the proper way.

I have to tell you this renaming a DC without going through the proper steps can kill a DC. Do you have others online or a back by chance?

At this point, should I dcpromo out the new 2008DC, removing from domain, deleting entries to OLDNAME in the domain, renaming then DCPROMO back into the domain with the new name? i would have to replicate from another site, but that should be OK, it's a solid connection.

I would remove this DC from AD.

Run metadata cleanup to  make sure no lingering objects are left behind.

Delete all DNS records.

You can then promote the DC again with the proper name. If you are going to demote go a head rename the server when it is not a DC you can then promote and you will be done

I've done the same thing, but I changed the name on the old server and the new server.  I've already transferred operations to the new one (that is now getting all the errors because I didn't change the name following the correct procedures).  I think I need to transfer operations back to the old computer, demote the new one, change the name, then promote it.  Is that right?
