How did you try to hook them up??. Do you have a wireless modem connected to the PC??. If so, are you getting any signal?? That might be your problem, low or no signal. Once you get a good connection, Windows itself will step you through the procedure to run remote desktop. It's a matter of having permission on one computer to access it. However, there's bound to be a website showing you how to do it...try these....
