Lsass.exe??? WHat the hell

[Sovereign]

My laptop all of a sudden shut off by "NT AUTHORITY SYSTEM". IT prompted something about a c:/widows/system32/lsass.exe file and a status code 128. Now, ever time i boot it up the same msg pops up and it just reboots. Whats going on???

[Chruser]

Possibly a virus. Use start > run, and type in "shutdown -a" without the quotes. That should take care of the message for you until you can deal with the problem.

Lsass.exe is a required system process of Windows

Don't know if that's the error you're getting, however..

Thats exactly wat is happening. -_-

WHen i went to the website though, it said a windows 2000 service thingy. My computer runs on the Home Edition of Windows XP

Boot with the Windows XP CD (hopefully you have yours).

Do the "Repair" option. That SHOULD replace/fix your lsass.exe. I just hope that it doesn't make you have to redo your Windows Updates again..

And your Home edition should look like the above, but with "Home" instead of "Professional"...

Nice, thank you for finding that bluecube. I shall try it when i get home.

My other question is: Could this file being damaged be the reason i couldn't turn on my auto protect option on norton antivirus, and why i got an error in the email scanning category. (This is before the system went whack)

Error: "AutoProtect is unable to start, Symevnt.386 is not loaded. You may need to reinstall Norton AntiVirus to correct the problem."

Don't know what the error you had was, though, so I'm just throwing some links around. Both basically just say to reinstall NAV..
