UPHClean and lsass.exe

by sheilakmcd / July 15, 2005 12:56 AM PDT

XP Pro SP1, all updates except SP2. Current AVG, Spybot, and Ad-Aware scans.

For about 2 weeks my applications event viewer has been giving the usernv eventid 1517 error on every shutdown or restart. I don't remember installing anything except windows critical updates and avg updates. I haven't made any changes in Services.

In my quest to discover what process is causing the hang-up, I installed UPHClean and set it to just report. It reports the problem is lsass.exe (516) HKCU(0x3d8)

File search shows lsass.exe in C:\Windows\system32 C:\Windows\ServicePackFiles\i386 and C:\Windows\system32\dllcache. AFAIK this is as it should be.

Tasklist /svc shows lsass.exe running ProtectedStorage and SamSs. Both of these services are set to Automatic and Running, which, to my knowledge, is how they have always been.

I'm at the end of my knowledge skills now. What do I do from here to discover which of these processes is causing the error and how to fix it?

Stopping and disabling these 2 services doesn't help. The lsass.exe now shows in tasklist as PID 512 with service as N/A. UPHClean still shows lsass.exe as being the problem.
Where do I go from here to solve this?

lsass.exe is a known Windows service that needs to run. However, there are variants that are viruses. The variants can either be a different name, eg lsasss.exe, or the same name, lsass.exe, but located in a different folder.

Have a look at this site, http://www.answersthatwork.com/Tasklist_pages/tasklist.htm
click the ''L'' button, and scroll down to lsass.exe for more information.

If the lsass.exe found by UPHClean is located in C:/Windows/System32, then it is probable that the one you have is ok, and UPHClean is declaring a ''false positive'', ie, it is ok but the program thinks it is not.

If the file found by UPHClean is lsasss.exe, or lsass.exe in a different folder, then you have a worm, or a virus.

I don't know anything about UPHClean but as it is a Microsoft product I wouldn't have thought it would report a false positive, (that very often happens with dubious trial anti-malware software where the makers want you to buy the full product).

I found this site about UPHClean;
http://www.windowsitpro.com/Article/ArticleID/42257/42257.html

and this earlier CNET forum thread about someone who had used it;
http://reviews.cnet.com/5208-6142-0.html?forumID=5&threadID=112143&messageID=1276248

If no-one else here can offer any suggestions, why not post the same question in the Computer Help forum on this site. You may be more fortunate there.

Good luck,

Mark

I have run AVG, Ad-Aware, Spybot, Stinger, CWShredder, Panda and Symantec online scans. No problems found.

But my computer is slow, especially shutting down and starting up. While searching for the cause of the slowdown, all I could find was this error in Event Viewer.

Event ID 1517 Source Userenv
The Windows saved user N+++++\Sheila +++++ registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use.
This is often caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account.

As stated, UPHClean reports that lsass.exe is the process that is causing this error.

I still get the error even when Tasklist /svc reports that all that is running when I am shutting down or restarting is:

tasklist.exe 1988 N/A

I am at a loss to discover why this started. And it may be a total coincidence and unrelated to my slowdown.

But it still bugs me, and I'd like to track down the problem and get rid of the error in Event Viewer.

I guess now I will uninstall the Windows Updates I have done is the past 2 weeks and see if one of them is causing the slowdown and/or the error.
