I have installed the latest VNC distribution on a Windows NT4 server (SP6)
but although it works okay, I cannot guarantee that it'll stay up for any
period of time.
Randomly, when I attempt to connect from a Windows 2000 machine using either
the VNC Viewer, or the Java Viewer, I get the authentication dialogue but
when I enter the (correct) password everything just hangs.
If I run the Java Viewer from the command-line, the hang occurs after the
client init phase but before the desktop name is displayed.
The VNC server is installed as a service on the NT server with local
administrator rights, using the default settings except for the password - I
have attached the output from Dr. Watson.
Any help would be much appreciated ...
