So I’ve got my own Active Directory server at home w/ multiple network segments. On one of these network segments, I’ve got a Win2008R2 server w/ a static IP address that needs to join the domain but isn’t on the same network segment as the AD server. When I attempt to join the domain I get the following error message.

Once I get the error message and do a reboot I’ve joined the domain w/ no perceivable errors except the one shown above. I can log into the server w/o any issues using domain user accounts and everything appears fine. Obviously not satisfied w/ this conclusion I start doing some searches and remove the server from the domain to see if I can repeat the above error message.

Finally after searching for an hour I stumble upon a similar domain joining error on Lumbgaps blog and add a domain suffix to my server via the advanced settings on my network card. Once joined, I remove the domain suffix w/o any issues. Seems the server was having a domain searching issue and wasn’t appending the right FQDN on the end of whatever it was doing. This fixed it.
