I have Real VNC 3.3.7 installed on both a Win2k Server SP4 and an NT4
SP6a server. In both cases I cannot connect unless a user is logged on
at the server. The VNC server is running as a service and does start

What configuration setting(s) do I need to change so I can connect to
the server when no user is logged on?
