lsass.exe system error

By arb5s ·
Hello,

I have an lsass.exe problem. In all the solutions I find on the net, people presume that you are still able to start your PC and end up on the desktop. My problem is that I can't even get that far anymore (I am now working on a different PC).

Here's what happens, I turn on my PC (power), Windows is trying to start up (I get the Windows XP pro sign with the cyclops horizontal bar going from left to right), than a black screen, and after a while a little window titled "ISASS.exe system error", message "object not found". The only thing I can do is accept (click on 'ok' or on the cross to shut down) and than the system starts all over again. Point is: I am completely unable to even end up in my PC. HELP ! Anybody can tell me what to do?

You will need to do a Windows Repair.

If those does not work, you need to do the In-Place Reinstallation.

Have you tried

Put in the Windows CD, and do the following:
Press start ----> Run ----> enter the following, without the quotes: "sfc /scannow" and press ok.

we need more to go on. do you think you may have the sasser worm? (iow, did you have adequate functioning anti-virus protection in place at the time this problem cropped up?)
or, did you have another problem and run Automated System Restore and *then* have this problem? (if this is you, check out possible hotfix at support.microsoft.com)
it is fixable for sure but we can't tell you how yet. here are some mroe quetions:
1. can you boot in safe mode? (apparently not, please confirm)
2. what service pack are you on? you'll need to get a firewall up quickly on any fixed/new os installations if sasser is your problem...
do you have enough hard disk space to install a second copy of xp pro in another folder? say for example, c:\winrescue. you will need at least 3 or 4 gb free i think

Can you repair it through Safe Mode, or through System Restore?
Also, you may get a little more time before shutdown if you do not click OK on that box.

I would suggest to first try safe mode and run the sasser fix utility. If it still continues, the file may be missing/corrupt or the reg. entries to the file may have been damaged. In those cases try inserting the Windows disk and using the 'repair' option to bring the system back, or remove the HDD and slave it to another system to fix the prob. or backup data.
