Help needed, lsass.exe startup error

post #1 of 6
Thread Starter 
I was wondering if anyone could help me work out an issue on my desktop PC running XP (I'm posting from my laptop.) Basically the problem is this: When I turn my PC on, it goes through the windows xp loading screen, then the screen turns black, and I get an error message related to lsass.exe, claiming that "The application failed to initialize properly (0xc0000022) Click on OK to terminate the application."

From what I've been able to gather, lsass.exe is "a system process of the Microsoft Windows security mechanisms. It specifically deals with local security and login policies." I've also found that because lsass.exe deals with some of the most critical data on your computer, it has become a huge target for some nasty viruses like sasser.

The issue most people seem to have had with the sasser worm was that their computers would shut down within 60 seconds. Due to the fact that my computer is producing a blank screen rather than rebooting every 60 seconds, I'm leaning towards the conclusion that I may have removed a .dll file that was needed to run a program essential to my startup process. I could be completely off, but it's the best guess I have at the moment.

I understand that I may have to reinstall Windows, but if it comes to that, I'd rather hear it from someone who knows about this, than keep prodding blindly at the issue. Any advice or solutions would be very much appreciated, thanks.

*note: Please forgive any spelling/grammar mistakes, it's very, very late.

Try booting in Safe mode and if all else fails perform a repair install by booting from your Windows installation CD.

lsass.exe is a service process for Windows that handles user accounts and access to the explorer. Many Services are collections of different processes that are critical to the operating system. However, some viruses and trojans have been known to embed themselves into the service. Either way, lsass.exe it should never be removed or stopped.

You're getting confused between lsass.exe and Issas.exe

Hey, wait a minute, the two files are the same! Well, not quite. The first starts with the letter lowercase l (L) and second starts with the letter capital i (I). The one starting with i (isass.exe) is a virus/Trojan but Windows users may easily mistake it for the important legitimate Windows Local Security Application Server process, lsass.exe.

The substitution is used in other areas too. The virus, Backdoor.NetDevil, is copied onto a computer with the filename of Kernel.dlI - except that the last letter is a capital i. So, because of the way fonts are displayed, Kernel.dlI (the ending here is .DLI) can look identical the all important Kernel.dll (ending is DLL).
