Windows won't boot due to lsass.exe

[Guest]

Hi
When I try to boot up my pc I am getting the following error

lsass.exe - System Error

An invalid parameter was passed to a service or function

I can't even boot up in safe mode to do a system restore.
Also I have downloaded all the latest critical window updates
and my virus and firewall software are also upto date

Any Ideas???

Have you tried a repair re-install using your XP CD?

Sounds like you have the Sasser Worm. You can download the Removal tool from
http://securityresponse.symantec.com/avcenter/FxSasser.exe

If he had the Sasser worm then shouldn't that file be "lsasse.exe" instead
of "lsass.exe"?

Aw, man. Sorry I can't be of more help. That's a security authentication
logon related file. If you have important data on the HDD you can probably
still get it if you put it into another NTFS system as a slave or secondary
master. Usually, a repair installation will at least let it boot under
"default" security templates, although the user accounts would probably be
trashed. There's a chance that HDD is failing. After you save any data you
cn, you might want to test it with the HDD's test utility.

Can you boot to the recovery console from CD and try a chkdsk /R on it? It
probably won't let you in as administrator, though.
