Freezing monitors and quick refreshes in VNC

Hello everyone,

I use VNC to display realtime data on about 10 monitors from a live feed
via the Internet. I am using Professional (including the German version
of Professional) and 98 on all of the systems. The program works fine
for the most part, however occasionally I get one of the monitors
freezing up for about 10 seconds. Lately, one of our machines does this
somewhat more frequently (i.e. 3 times in 2 hours). This machine uses
Professional in German, and is running no other programs. (Network is
10/100Mb using TCP/IP)

I have tried polling just the active window (which is all I really
need), and using VNC Hooks to tie the refresh rate to the timer. This
doesn't seem to help. Any suggestions?

Thanks for any help.

Steve,

When you say "one of the monitors freezes up for about 10 seconds", do
you mean that updates to the client stop for a while?
Are you sure you have the latest version of your network drivers
installed? Many problems with VNC over LANs turn out to be VNC showing
up problems with the network driver configuration.

Cheers,

Yes, I am absolutely sure that I have the most recent network drivers.  As part of the troubleshooting process, I replaced the network card (to be certain that it wasn't just a quirky card), the card I replaced it with is from Asante, and I had to go to their website to get the latest driver because I didn't have the drivers when I got the card.

Our one machine that uses Win98 has no problem, and the rest of the machines use German or American Versions of Professional.

Thanks for your help!

Steve
