“Failed to join domain” trying to add Windows 2008 R2 Core to domain


Today I was using SCONFIG (if you don’t know what SCONFIG is, check out these posts to add a Windows 2008 R2 core server to an existing domain. I had set the IP address and ensured that the domain name and credentials are correct, but I kept getting ‘failed to join domain’.

I tried pre-creating the computer objects in the AD but to no avail. Finally after some troubleshooting it turned out to be a most basic issue: the primary DNS IP was not set correctly. After setting that (again with SCONFIG) I was able to add the Windows core box into the domain.

    I'm in the same boat.  I have a virtual machine running Windows 2008 R2 Core Edition running in a Test network environment.  We regularly blow away the other servers and snapshot in newer machines from our Production environment.  Because of this the Core server has to be readded (manually on the AD server) so that it can be removed from the domain.  Well today, I can't get it to readd to the domain.  It can ping the AD server without issue and I my account is valid and not locked out.  Arvind, did you ever find a solution to this?
