Our location has XP on machines in a lab that is
set off by a separate firewall, and also the XPs
are configured (and this cannot change) to turn
off certain things like MS remote desktop and it turns
off
other internal firewall program settings and ports.

None of these settings or setup can change due to
security policy. Nor can I experiment with any to
see what would work.

I am running vnc server on this XP, and from machines
outside this lab, where I am, when I use vncserver,
I do get the prompt for password, and the vnc window
appears for 1-2 seconds, then goes away, with the
message vncviewer: VNC server closed connection

Rarely, if I click somewhere in this window while it
is
up, I can actually operate in it for maybe a minute,
and then it goes away as before.

I've changed the display port number, using 8080 or 80
or various others, and that does not seem to be
the problem, as I always get the prompt for the
password
and the XP vnc window always comes up for those one or
two seconds.

And same thing happens when I attempt to connect via
browser,
except the message in browser window when vnc window
goes away
is java.net.SocketException: Connection reset by peer.
I'm not aware of any other ports that vnc uses that
would have an effect on all this or that I might need
to change.


What I'd like to know is what is happening that
allows the connection at all, and then what happens
that causes it to go away ?

I realize I've not given a lot of information as to
the
details of the lab firewall or the specifics of what
all is turned off in the XP since I don't know.


Thanks - mt
