Please excuse my ignorance here, but why not just use a remote desktop client?  I use grdesktop to connect to some of our Windows servers at work.  If I am outside of our domain, so long as I am logged into our vpn, I can connect to the servers (and be looking at the Windows desktop on my machine).  Actually, something recently "broke" somewhere (Firewall perhaps? Can't locate any rule in the firewall that is disallowing the connection...) and I can no longer do this from outside of our network, but I'd like to gain a better understanding of how to fix the issue.  Anyway, perhaps the remote desktop method would also work for you.  The Windows machine would just need to be set up to allow remote access.
