I'm having this issue as well. It started about the time we installed FR2
or Windows 2000 SP2. I am currently working with support as well. They are
telling me that no one else has reported the issue. How interesting.

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=3D
, that was having a critical problem. Periodically, we would see the =3D
processor fall to almost 0% utilization and the users would experience a
=3D
5-30 second delay in keyboard response or pull-down/pop-up menus,
although =3D
screen refreshes were fine. It was severe enough that we had to roll =3D
back.=3D20
We applied the following MS HotFixes: Q317357 & Q320261. The later =3D
required modifying the Registry Flush rate from the default of 5 sec. to
=3D
30 sec. While this reduced the problem from happening every 5-8 minutes
to =3D
once every 90 minutes, it did not eliminate it all together.=3D20
After much hassle attempting and finally getting a Live Remote Debug and
=3D
Kernel Memory Dump (can't have more than 2GB physical RAM and must only
=3D
have a single hard drive!), we found out that Citrix' TZHOOK.DLL was a =
=3D
part of the problem.=3D20
This DLL tracks the time zones for each user session and can be turned
off =3D
in the Farm Properties of the CMC. Once we did that, our processor =3D
utilization nose dived from 80% to 25% for 90 users.=3D20
I hope some of you will find this helpful and won't have to go through
the =3D
long, painful process we did.=3D20
