The best general method for setting up VNC on any NT family OS is the following,
done with a clean install preferably:
<quote src="Floyd Russell">
"1. Install VNC
2. Install VNC Service
3. Start->Programs->VNC->Run WinVNC(AppMode)
4. Enter your password, this is for the current user.
5. Start->Programs->VNC->Administrative Tools->Show Default Settings
6. Enter your password, this is for the local machine
7. Close WinVNC
8. Start WinVNC Service
You may need to start the service helper if you want to modify settings of
the winvnc instance running. This problem is due to the way Terminal
Services operates, since you are working in a virtual desktop."
