Hi Max,
Remote Desktop uses port 3389 to connect, while you have to permit Remote
Assistance, and even the one in Windows Live messenger, to get through the
Internet. In your Firewall, look under "Exceptions" and you'll see three
distinct srevices to enable, as follows:
-RemoteAssistance,
-Remote Assistance - Windows Messenger and Voice
-Remote Desktop.
I hope this helps

Samuel.
