how do I proxify Remote desktop connection

Hii..
I have been connecting from a Univeristy A computer to University B computer, for my project, via remote desktop. Today, while trying to make the University B more secure, I accidentally added the entire University A ip group to the blocked list on University B computer.
Remote desktop should still be active on the University B computer, I cannot connect using my current ip. I know that Tor can be used a proxy server, and was thinking of using it like that. I tried and could use firefox/internet explorer to go through the Tor proxy. However I cant find a way to redirect the remote desktop to use the Tor proxies.
I dont know a lot about networking. It maybe something very simple, so it would be great if somebody could please suggest a way out.
Thanks a lot for your help

I am assuming that you can't actually gain physical access to UNI B computer. and that you're trying to fool it into thinking your connection is coming from somewhere else....

as far as my knowledge of TOR is that once it's installed on your machine ALL traffic from that machine will be "proxied" through another site...however if the UNI B is on a seperate physical site with seperate internet connection, well there maybe firewall rules in place to stop unsolicited RDP traffic from unknown (TOR'd) networks...
