Cannot add new PCs to the domain

I have a Windows Server 2008 R2 DC, and am currently attempting to add computers to the domain I have created.  I just recently created a GPO for the domain, as well.  Before creating the GPO I had no problems adding PCs, but now I keep getting an error stating the following:

"Changing the Primary Domain DNS name of the computer to "" failed.
The name will remain "domain name".
The error was:

The RPC server is unavailable."

As far as i know, I didn't make any changes in the GP regarding an RPC server, so I'm not sure where this is coming from.  Can someone help?

I typically would say "what happened last" which you have stated.  Try removing the newly created GPO and give time for replication if you have other DC's.   Then attempt to recreate the error again.  If no error, then we are on the right track and the problem is with the GPO.

Hi,

can you provide which GPO setting you have used and which GPO you have created or modified.

Unlink the GP/revert the changes then try again. Most likely your GP is not allowing you to write the changes.

are trying to join the domain using a domain admin account? also make sure you have your DNS setup properly either through dhcp or staticaly assigned. also did you remove admin rights through your gpo  from the workstations?

Also, specifically what did you set in the GPO?
Are their any DNS specifications?
Is DNS pointing to the primary DC?

Ok I unlinked the GPO and removed and re-added the PC to the domain.  No problems, so the issue must be with the GPO...I am looking more at it to see if I specifically changed any DNS settings...

I removed the settings I thought could have been causing the problem, then re-linked the GPO.  Ran gpupdate on one of the clients, and now when trying to add a user clientside I get an error stating:

"The user could not be added because the following error has occured:

The trust relationship between this workstation and the primary domain failed."

Does anyone know what in the GPO this could be referring to, or at least what section the setting could be listed in?

Hi,

can you share which setting you have used.

From the error it seems that trust relationship is broken. Try to rejoin the system to domain again.

I just had to recreate the GPO.  I still don't know what changes I made that caused the issue, but it's working now.  I am awarding points to first responder.
