Hi Steve,
Regmon and filemon will blow up a server if it's gets hammered too heavily.
Some versions of regmon are more "stable" than others. About 18 months ago I
tried using the then latest version and I crashed several 2003 servers. Went
back to a version I've been using for years (4.32) and had no problems. Not as
pretty, but it gives me what I want and it's reliable ;-)
As far as profile unloads are concerned, userenv debugging
(http://support.microsoft.com/default.aspx?scid=kb;EN-US;221833) can give you
some fairly useful information, even for logout, and may point you in the right
direction. You will be looking for gaps in the timeline to indicate what to
look at.
However if it is a registry unload issue, I'm kind of surprised that UPHClean
isn't giving you some information. Having said that, a common culprit is
%userprofile%\local settings\Application data\windows\usrclass.dat which is
reponsible for the %usersid%_classes entries under HKEY_USERS or
HKCU\Software\Classes.
If you're using folder redirection, then don't forget that the user profile
consists of files and directories as well. Had a customer recently with major
logoff delay issues that turned out to be due to mishandling of the coookies
folder and opportunistic locking on the server hosting the redirected folder.
At any rate, process explorer (sysinternals) is probably the tool of choice to
try and find out what's stuck, but filemon and regmon will give you good
background information on the processes involved.
regards,
Rick

I've had it blow up a W2K box while diagnosing a problem with Attachmate & SNA.
There appears to be an interaction between regmon and these two apps. I still
use it to diagnose other applications but it will consistently do bad things
with Attachmate & SNA. It either crashes my session or the whole system.

Thanks that was could be a big help. I will try it next time it happens.
As an asside, has anyone out there had regmon blow up thier servers. Twice now
I have used it and it has crashed our w2k3 servers.
We are thinking about buying it but know I am thinking it won't work for us.

Use proces explorer and search for the handle.

We have UPHclean but it is not catching these ones. No processess running
under user id. Can't delete profile out of memory and thus profile on server
(docs and settings) sitting there.
