We seem to have an issue in our environment whereby when a user logs off,
occasionally it will cause the entire server to pause for a period of 10-30
seconds (sometimes more, but that is extremely rare).
I found the following Support Document for Windows 2000 and Server 2003
Lanman Server and Workstation services as described in the article.
I also found http://www.yqcomputer.com/
CmpRegistryLock value from 30 to 60, but this doesn't seem to have had any
We previously just had a Windows Server 2003 (no SP1) environment, and at
the beginning of the year moved to a Windows Server 2003 with Service Pack 1
environment (on both Domain Controllers/File Server/Terminal Servers) and
then the problems have arisen.
This issue seems to affect both Admin and Non-Admin Users and seems to
happen when a server has more than 10 users on. I have tried perfmon and
userenv debugging, but as the server 'pauses' there is no output displayed
from either (permon has no data and userenv debugging pauses as well). Any
mouse clicks/keyboard entries are queued and as soon as the user has logged
off, the server is back to normal and any queued commands run.
I've rebuilt our Terminal Servers from scratch again to rule out any issues
with the image, and the problem still seems to exist. During the pauses, the
CPU and Memory aren't high at all (less than 10%) so I'm confident it isn't a
resource issue. I have also tried enabling Disk Write-Caching and Advanced
Performance as per KB32446 but that has had no effect either. We have two
models of IBM Blade Servers - ones with local SCSI drives and ones with local
EIDE drives and both have the issue. I've updated all firmware to the latest
revisions as well, but with no success.
Does anyone have any ideas? Thanks.
