I am trying to log into my work computer remotely. I am using Windows 7 on my laptop. I have created a vpn connection to the network, and I am doing a remote desktop connection directly to the ip of my box (192.168.xxx.yyy).

If I do a remote connection to a different box, running xp, it goes into remote desktop mode immediately and I see the windows login dialog as I am used to seeing.

If I try remoting to my box, which is running vista, I do not see the remote desktop mode, but an additional dialog on my local machine asking for my credentials. It defaults in my local username. It allows me to log in as a different user, but the domain it has is still my local domain, not my work domain, so none of my usernames or passwords work. There doesn't appear to be a way to change the domain.

Trying to hit several more boxes, it appears to act differently on xp and vista target machines. I feel like this must be a configuration issue, but I am not sure what the problem is. Any idea on how I can connect?
