I built my dad a machine and enabled RCP on his computer. I also forwarded port 3389 on the router at his place so it would work. When I try to connect to his IP, the connection fails; when I try to use easyconnect, is says my connection isn't good enough, even though I pass every step of the MS connection test; when I use the invite method it says the password is wrong even though it isn't. We're both using W7Pro and Dlink routers. What do I need to do to get RC to work?
