I work remotely for my company, and use VPN to connect to the main office network and domain. The domain controller there is a W2k3 box. The workstation I use was joined to the domain before I moved it here, and so I can sign on using my domain credentials. However, if I need to sign on as a different domain user, or if I need to join another machine to the domain, I can't.
When I try, it says that the domain controller could not be located, or that the domain is unavailable.
Now, to compound this issue further (in my mind at least), I use domain credentials when I sign in to the VPN, and I can use any available login for that successfully. In the tcp/ip setup for the VPN connection on my workstation, I have added an entry for DNS that points to the domain controller.
Still, no dice. I'm in dire need here. Any thoughts?
