I've been having some issues with my remote desktop. I've set everything up correctly as far as firewalls and whatnot and it does work initially. I can access my XP SP2 box from anywhere for the first few months. However, after that time when I try and access the XP box, the remote desktop program simply goes grey for a moment as if its connecting then nothing happens. I've checked all ports and they are set correctly. Does anyone know what I'm doing wrong?
