"The connection closed unexpectedly"

I would say that re-doing the cable ends on the patch cables would be a good
first step. Perhaps buy an inexpensive ($20-30) cable tester to make sure
the signal is good all the way through. Also make sure you don't have any
crossed wires. Further, I would make sure you've actually got CAT5 cable,
and not CAT3 (phoneline). One of my co-workers was living in an extended
stay motel for awhile when he first moved here and their network kept
crashing whenever he hooked up his VOIP phone. Turns out they were wired
with standard phone line, and not CAT5 ethernet cable, and the
CAT3/Phoneline couldn't handle the load and dropped the signal.

Hi James and John,
Just reading a note that you wrote to Ben. I had the same problem the other
day with my machine and all we did was to uninstall and reinstall VNC and
the "connection closed..." message quit.
Now, for the 10054 error. I originally wanted to wipe the drive clean and
redo everything, but now I am starting to wonder. Two computers are
connected to the cable modem via a router, and the port forwarding is right.
I had John Aldrich drill that into my thick head about 20 times before I got
it and now I know it is right.
We direct-connected the cable modem and the computer and still got the 10054
error. The people that live upstairs are also tied into the network, and he
came down one day, wiggled a few ethernet cables and got his internet to
The first question is could VNC be sensitive eno! ugh that a momentary loss
of signal could cause it to reset the connection at the server end? That is
the end with the loose ethernet cable(s), and that does not implicate the
router if the connection ends are loose? Also, if the cable modem is now
letting me in and then resetting the connection does that leave the cable
modem out of it? I can have the office manager go to Adelphia and exchange
modems and hope that is the problem, but I want to believe that the ends of
the RJ45 are suspect cuz that is the easiest, quickest fix.
Please let me know what you think. I am going to send this to John Aldrich
too cuz I need and want the Best Opinions on this one. I saw nothing in the
mailing list questions that even came close to answering this problem. I did
do my homework as best I could before coming to both of you for help.
We are using VNC to enter motel reservations remotely from either my comp!
uter or the Owner's computer into the Motel Office computer. February
starts the bookings in earnest.
Thank You for your Help Gentlemen,

OK, the thing to check at this point is the reason that VNC Server closed
the connection - check the Application Event Log of the server computer for
messages starting "Connections: closed", from WinVNC4. Obviously, you'll
need to look for messages corresponding to the point at which things started
