We have been experiencing this issue for a few weeks. I contacted MS today,
who agreed to send dskcache.exe via email. I was also told that they are
currently working on a hotfix which would not be imminently available.
There was mention of inclusion in SP5, which considering the wait for SP4 is
a long way off.
During the conversation I did learn that SP4 is likely to be released next
week.

This is exactly the behaviour we are experiencing and for which I posted
a question on this list a few weeks ago.
We will see if this helps...
Anyway thanks for your input Frank!

Was this from a ticket you had with MS frank? This looks exactly like
some symptoms Brian madden was fighting with 3 or 4 weeks ago. They had
MS, HP, ISVs all involved.

SYMPTOMS=20
=3D=3D=3D=3D=3D=3D=3D=3D=20
A Windows 2000 Terminal Server may stop responding or pause for a few
seconds with the follow symptoms:=20
1) While typing a Word document, characters are not displayed until
after
the pause is over.=20
2) Keyboard and mouse inputs are queued but not processed until after
the
pause is over.=20
3) Live Perfmon graphs have missing data points during the pause.=20
4) All applications system-wide appear to hang during the pause.=20
5) High CPU usage in spooler when large number of users connected=20
CAUSE=20
=3D=3D=3D=3D=3D=20
The unresponsiveness is a delay in processing due to contention. By
minimizing the cause of contention, the delays are reduced.
WORKAROUND=20
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=20
The Terminal Server needs to be running at Service Pack 3 prior to
installing the hotfix mentioned in this article.=20
After you install this Windows 2000 hotfix and restart your computer,
you
must also turn on the Power Protected write cache option for each disk
that
has write caching enabled and has its write cache protected against
accidental loss of power. To configure the Power Protected write cache
option on the selected disks, use the Dskcache.exe tool. Dskcache.exe is
available separately.
For additional information about the Dskcache.exe tool and how to enable
the
"power protected" write cache option, click the following article number
to
view the article in the Microsoft Knowledge Base:
KBLink:811392.KB.EN-US: Obtain the Dskcache.exe Tool to Configure the
"Power
Protected" Write Cache Option=20
If you run Dskcache.exe without any parameters, the current write cache
settings for all hard disks are displayed. For each hard disk currently
present on your computer, the following information is displayed:
Disk device:=20
Volume name of the form:=20
\\?\\<SCSI <file://\\?\\<SCSI> DEVICE ID>=20
Current Settings:=20
Write Cache is [ enabled | disabled ]=20
Power Protect is [ enabled | disabled ]=20
To enable "Power Protected" write cache on a disk drive, use the 'p'
switch.
For example, the following command would enable "power protected" write
cache on the C drive:
dskcache +p c:=20
The output will look like this:=20
Disk device:=20
\\?\\<SCSI <file://\\?\\<SCSI> DEVICE ID>=20
Current settings:=20
Write Cache is enabled=20
Power Protect is disabled=20
New settings:=20
Write Cache is enabled=20
Power Protect is enabled=20
Note: The Power Protected write cache option can only be enabled for
disks
that are currently present. By default, the Power Protected write cache
option is disabled. As a result, this option is disabled for any disks
that
may be added after you apply this setting. If additional disks are
added,
enable the Power Protected write cache option for those added disks for
the
setting to take effect.
Finally apply the registry settings under the "Terminal Server's
Registry
Settings" section to the Terminal Server. If you are using a file server
to
share data, roaming profiles or redirected home folders for Terminal
Server
users, apply the registry setting under the "File Server's Registry
Settings" section to all file servers.

This hotfix does not address Terminal Server pauses caused by registry
contention from applications or slow Citrix clients using drive
redirection.
