But I can connect to many other remote servers that are configured in
seemingly the same way with no problem.  What specifically am I
looking for in terms of Group Policy settings?

It can't be anything that would cause a complete block to the VNC
program because this problem only occurs between our corporate domain
and this sepcific server.

Is there anyway to find out what VNC viewer is doing when it
disappears?  Does it log what it is attempting and what is is failing
at?

Thanks,
Chris K

You could be on to something with the domain-issue there. But probably not
what you seem to think... Try asking your systems administrator (whoever is
in charge of your domain's Group Policy) if they have configured Group
Policy for those systems that might be blocking the VNC application, or
perhaps a windows firewall policy, or something else like that. Such things
would not apply to a system in a workgroup.

Subject: VNC Viewer 4.2.5 disappears

I'm having a problem with the Personal Version of RealVNC Viewer 4.2.5.  I'm
running the Personal Edition of the server (4.2.5) on several different
Windows XP SP2 computers in remote locations connected by different ISPs.

When I try to connect to one of the servers from my computer the VNC
application disappears from sight as soon as you click OK to open the
connection.  The process is still running in Task Manager and you can open
as many attempts as you want.  When I put the computer to sleep or otherwise
interrupt the internet connection, all of these processes will come back
with error messages saying the connection was closed and then die.

Fine.  However I can connect from another computer in my office with an IP
address on the same subnet.  It works as you would expect.  The only
difference between the computers is that the one that doesn't work is on a
Windows domain, and the one that does work is configured as part of a
workgroup.  I have tried this on another computer which IS part of the
domain (and it doesn't work) so I am wondering if I am on to something.  Is
this a known issue?

Furthermore, at first the logs on the remote computer indicated
"Connections: closed 193.251.51.217::2815 (Requested security type not
available.)"
This seemed to be a lead, however it does not produce these warnings any
longer.  In fact there is no record of any connection attempts any more, but
the symptoms are the same.

Can anyone help?
