I'm running WinVNC (aka Ultr@VNC Win32 Server v1.0.0 RC 18) as my server on my Win XP Pro SP2 home PC. I'm using vncviewer 0.6 on my Nokia 770. When I put in the information for the VNC server on the 770, I have to use the format of "ipaddressort", e.g. "192.168.1.3:1234". I have no issues running it from over the LAN nor over the internet using my cell phone provider. Good luck with it!
