There were many issues with Gigabit cards and the results were exactly what
you have described. In some customers we simply had to disable them and use
100MB ones. That fixed all the issues.
You may give that a try for testing purposes.

When you say the other servers have the same problem, presumably you mean
the network queue length? I cant imagine it will be, but try add the Bytes
Total/s and see if the LAN's throughput is saturated. Are their functions
"slow" at all? ie, bringing up directory listsings or working with the sql
server?
Whats the backbone of your network, switch/hub/make wise?
Oh, and its Xeon, not Xenon ;)

We are running office XP Pro Enterprise SP3.
Yes we are running Dells with brodcoms on the 6 citrix servers but the
other servers are Dell with installed 3Comm Gigabit NICS that we
installed and are getting the same problems. BTW: these problems do
occurn on the LAN and the sessions that are frozen do show active.
Thank you for the suggestions tho,
Bruce Jarrett-Norton

If its easy to do, try a different NIC in one of the MF servers and see
if that helps, people have had various problems with broadcom nics (I
assume you're using Dells??). But have a look at the following first-
As for the stuttering, what happens if you're on the LAN with the
servers, do you get this? If not, I'd suggest looking hard at bandwidth
usage on your external connections, they may be very well saturated.
(Also check ping times over them!)
The frozen sessions I'd hazard a guess at being sort of the same thing,
but more extreme. Does the session show as Active or Disconnected when
they report this? You might find setting up the whole Keep Alive keys
thing will help this a little - they will be disconnected rather than
frozen!
There may or may not be something deeper going on, in which case someone
else may well provide more of an insight, but the above is what I'd look
at!
