Well, what i did is run Remote Touch Server on your pc, and that will put it into the notification tray. From there, I right-clicked and went to "Setup" and left the port, picked a password and download directory. Then on the ppc, loaded remote touch and in the setup typed my computers ip (if your not sure, just go to
http://whatismyip.com/ ) and make sure the port number matches the one that was in the server settings on your computer, and then type in the password. Hit connect and it should work, otherwise, something might be wrong. If you are connected through a router, you may have to enable port forwarding, but I don't know how that exactly works.. hope this helps!
so far I am loving this program. It runs faster and smoother than any other remote desktop program i have tried so far and it works great!
