Are you using strictly native drivers?

I've been working on the same issue for 8mo now. I built a fresh XP
farm on 2k and I applied the first fix (registry flush) which did
nothing for me. I'm now at level 5 support ,whatever that is, at MS and
they can't figure it out. They feels it's the print spooler causing the
delays. But my CPU just spikes once in awhile.
I also have the Local Time zone unchecked and I'm running FR2. No
change. Users are still complaining of delays, even on the LAN.
Did you spend time investigating printer auto-creation as the problem??

This makes sense...if all of your clients are in the same time zone
there is
really no need for this box to be ticked the server time should be
alright,
though it is by default.
Find the setting by right clicking on the farm name in the CMC choose
properties from the popup and choose the Metaframe settings tab and
uncheck
the box that says use local time of ICA clients.

We have a farm w/ 75+ that we upgraded from Win4.0TSE/MF1.8 to
Win2k/MF-XPe=3D3D
, that was having a critical problem. Periodically, we would see the =
=3D3D
processor fall to almost 0% utilization and the users would experience a
=3D3D
5-30 second delay in keyboard response or pull-down/pop-up menus,
although =3D3D
screen refreshes were fine. It was severe enough that we had to roll =
=3D3D
back.=3D3D20
We applied the following MS HotFixes: Q317357 & Q320261. The later =3D3D
required modifying the Registry Flush rate from the default of 5 sec. to
=3D3D
30 sec. While this reduced the problem from happening every 5-8 minutes
to =3D3D
once every 90 minutes, it did not eliminate it all together.=3D3D20
After much hassle attempting and finally getting a Live Remote Debug and
=3D3D
Kernel Memory Dump (can't have more than 2GB physical RAM and must only
=3D3D
have a single hard drive!), we found out that Citrix' TZHOOK.DLL was a =
=3D
=3D3D
part of the problem.=3D3D20
This DLL tracks the time zones for each user session and can be turned
off =3D3D
in the Farm Properties of the CMC. Once we did that, our processor =3D3D
utilization nose dived from 80% to 25% for 90 users.=3D3D20
I hope some of you will find this helpful and won't have to go through
the =3D3D
long, painful process we did.=3D3D20
