The rdesktop (and GUI frontends) Remote Desktop client on Linux is perfect for this. Supports the Windows RDP protocol. All you need is to find the raw connection data (if they don't give it to you, e.g. if they use "remote desktop connection files"). We have various Windows servers at work yet no developer uses Windows (it's all OS X and Linux).

Whoa very cool! Never heard of rdesktop before but I'll definitely check it out. Thanks!
