I have to say, it looks like you found the culprit, all right. Not sure why
it would bother just two machines, but sometimes software will do strange
things. :-)

Gents,

First, Wez, I meant my five separate machines are now set to five separate
ports (5900-5904) for VNC.

But John got me thinking, as I was still wondering about the other machines
on the LAN.

Running the WinGate management panel on the server/router machine, I saw
that WinVNC4 was one of the networking apps being shown as active on this
client computer ... as it should be. It was also showing UPS and Iconclnt
(both my power line monitor), WMP54GV4 (the wireless access point), Vsmon
and Zlclient (both ZoneAlarm), Eudora (as I'm writing this), and Firefox
(as I'm searching for answers).

Thinking that perhaps -- since every network activity (LAN or WAN) is
monitored by WinGate -- it was hanging port 5900 by simply monitoring the
process while it itself was using WinVNC on port 5900, I changed the
WinGate machine's VNC port to an arbitrary 5907. And voila, 5900 then
worked on this client machine. I changed the WinGate machine back from 5907
to 5900 and this client VNC stopped functioning on 5900.

My network knowledge isn't good enough to explain why, but the presence of
port 5900 on the server/router denied this client machine's VNC the ability
the use port 5900 -- and did so on one other client machine. That would
seem reasonable ... except that it didn't bother the *other* two on the LAN
using port 5900.

And John, there is no tunneling running in WinGate. Neither VPN nor the
WinGate port mapping service is in use. (I use SSH, but over port 22, and
not while I was trying to solve this problem.)

Enough for now, I think, unless there's something I can report that would
help someone else with this problem.

Many thanks,
Dennis
