Lsass.exe problem

H

Herb

I started having problems with Lsass.exe on my Windows 2000 PC, i.e.
occasionally Lsass.exe starts running and takes over all available CPU
resources, and in a rather 'aggressive' way, i.e. the whole system
grinds to a halt and apparently all I can do is restart the PC -
although it takes ages for all running processes to close, and when this
Lsass.exe problem happens it is very tempting to just 'pull the plug' :-(

This page:
http://www.liutilities.com/products/wintaskspro/processlibrary/lsass/
says lsass.exe "is important for the stable and secure running of your
computer and should not be terminated", or it could be trojan or a
'downloader' and "should be removed immediately".

However, I am a little reluctant to run the 'free registry scan'
available from the above site in the form of a program called
registryboosterplib.exe

This appears to be relevant: http://support.microsoft.com/?kbid=842382,
but I'm not sure I understand the issues listed under "Causes".

The first item under "Symptoms" is definitely true, but where do I find
the "Directory Services event log" so that I can check the second item
listed under "Symptoms"?

Thank you.

Is this a DC? If not the article probably doesn't apply. Say no to "registry
cleaners" Check the system Event logs for error details.

Thanks for the quick reply.

I don't even know what a Directory Service is, so I guess the answer to
your question is no :)

It's a normal, stand-alone Windows 2000 PC.

Please excuse my ignorance, but where do I find the system Event logs?

Thank you.

Found it, and it would appear that my system does indeed have some
problems, although I have to investigate further before I can ask a few
more specific questions.

I ran a system scan with F-Secure, and it did come up with several
'trojan downloader' instances (whatever they are!?), apparently
contained in my Thunderbird Junk and Trash folders.

F-Secure was unable to remove them, but the problem appeared to persist
even after I emptied and compacted the Junk and Trash folders.

To make matters worse, Windows 2000 now consistently comes up with BSOD
towards the end of the F-Secure process, saying something like
"Unexpected kernel ... trap" and "Physical memory dump".

Any suggestions?

Thank you.

If nothing else you can at least recover your data from the parallel install
prior to rebuilding the operating system.

This article may also help you.

Hi Dave,

thanks for the link.

My user data are safe (I synchronise all my data on a daily basis with a
full backup on an external USB drive), but I'm hoping there might be a
less drastic solution to the issues I described than re-installing the
OS (either parallel or otherwise).

Here are the symptoms again:

Not really. Try something other than F-Secure?
