Hello Ben - hope I'm not teaching Grandmother to suck eggs!
Are all XP 5.1 versions patched the same?
Missing/incomplete patches can cause frustrating problems.
BUT .. Your intermittant problem sounds more likely to be network hardware
trouble.
Questions that could be asked ......
Are all remote systems identical hardware?
Same NIC, router, hubs.... blah blah?
Anything common about the ones with intermittant failures, not common on good
systems?
Anything strange about the surrounding environment of the dodgy ones?
If you want to be a network detective...
Anything odd when packet sniffing your VNC connection protocol?
Tried and tested methodology - long term and a pain.
Replace "dodgy" connection equipment one bit at a time with equipment from
"good" connection.
Including network cables!
Put "dodgy" equipment into "good" connection.
I'll leave you to work out the rest.
Eg.. Swap (and reconfigure if necessary) NICs - run for a while
Swap and reconfigure routers - run for a while
and so on
and don't forget to swap cables!
"Eliminate the possible and whatever remains, however improbable....."
Win-doh! doesn't respond well to misbehaved NICs and routers.
Another thing - may or may not be relevant....
On computers with rear power switch and front panel pseudo power switch.
Some NICs do not totally reset with soft boot, or even front panel switch
off/on.
Some remain "alive" and have caused me problems in the past.
I've had to do a complete cold boot from the rear panel power switch to see
problems disappear.
Did I mention swapping network cables?
Hope you're not monitoring sheep stations in the outback or suchlike, as this
sort of exercise can be very time consuming.
