Good Afternoon All,

I have been a member for a couple of months now, but have not posted before, as I have been able to solve any problem by reading others' similar problems and the solutions.

However, I am stymied on this one:

I have just booted up a laptop (Compaq Presario - XP Home) that has been returned from a work colleague and have been confronted by:

lsass.exe - System Error

An invalid parameter was passed to a service or function

(That is LSASS.EXE)

On selecting OK, the computer reboots and presents me with the same message.

I have never connected this computer to the internet, purely using it as backup for an accounts program, and are therefore unable to post a log of the problem.
I have been assured that the computer was never connected by the borrower, but he has three teenagers at home, so one must draw ones own conclusions.

Is there available a download/patch that I could install to rid me of this problem?

If the comp was hooked up to the net you may have the Sasser Worm. See the info in the link below for details on identifying and removal.

Many thanks for that, Buddy215.

It would appear that this is the case.

I have downloaded the fix to a CD.

All that I have to do now is figure how to get it onto my laptop without losing any data.

Does the laptop have SP2 on it? If not, I'd suggest getting it as soon as you are back up and running. It'll fix the vulnerability for the Sasser worm (but won't fix the worm itself).

This bugger has been around for a while, so the fixes are fairly well known and fairly stable.

Let us know what you can and cannot do with your laptop and we'll make some suggestions on how to get into it.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
