I'm running VNC server on a win2000 server SP4 domain controller, but after
the third or fourth login i can't connect to it anymore...i have to phone
someone at the office and have them restart the service, but the service is
already running!
I have it installed as a service on several machines and OS's without any
problems, it's only win2000 server that seems to hang like this. Any ideas?
