Can't connect to RDP over VPN

I have a small problem here. My work does not have port 3389 forwarded, so we use VPN. I can establish a VPN connection w/o issue, and bring up MSTSC no problem. I enter the non-FQDN computer name I'm connecting to, and being Vista (RDP v6), all I get is a username/password field (no domain). When the remote computer comes up in the new window, only my domain is available in the 3rd box for the remote login window.

I've tried the UNC format (both before the RDP session is started, and after in the remote computer window), putting domain\username as the login, then my pass as usual. Doing that shows "domain: work" in the MSTSC login box, and greys out the domain field in the remote login box, but I get the typical "The system could not log you on. Make sure your User name and domain are correct".

Of course, my username/pass ARE correct. I use RDP all day at work. I've tried with both my domain admin account and my regular user account (which has RDP rights), no go.

What could be causing this?

My domain is a Win2k3 domain, as well as my work domain. The computer I'm connecting using VPN and RDP is a Vista Ultimate machine. I've also tried connecting VPN and RDP from my Win2k3 box (RDP v5), but that gave the same error.

Check for the rdp connection is turned on
the pc u r connecting.

Also check the users rights & permissions. By default administrators have the rights.

What exactly do you mean? I use RDP all day at work and at home. By connecting through the VPN, I should be able to remote into any computers at work that have RDP enabled. I am using an account with RDP priviledges (as I said, I used RDP at work all day long).

I actually get the server screen on my 2nd monitor (which I use for RDP sessions). The login box is there on the remote window for the server, however, my HOME domain is the only domain it shows in the pull-down list. I can select "blank", then try putting my credentials in a domain\username format (which greys out the domain list), but I still can't log on.
