lsass.exe "object name not found"

Everytime I try booting up my pc I get this error message:

lsass.exe "object name not found"

All I can click is "ok" and then it reboots. Then it cycles through again.

I cannot get into safe mode either. This sucks, because i have a report to write. :0(. Can somebody help me?

P.S. I even tried doing the "in place upgrade" and i still get the same error message.

You should go here and do what it says. If you have problems with it post again and I'll break it down for you.

how can i run the tool if I cannot get into Windows? The only thing I get is a popup with the error message "lsass.exe object name not found" and the button "oK"? Then it reboots...

Actually get this tool and burn it save it on a disk and boot into safemode and use it. I'm assuming you have another computer if you can post here. To boot into safe mode press f8 repeatedly when you start the computer.

What he needs to do is get his hands on the XP installation disk he has and reinstall XP. Not format and reinstall XP, just reinstall XP. That way his data and files are saved, but there is a fresh XP on there with the missing exe file.

Of course, this means you would need your legal xp install cd.

Sorry for not reading the whole post again. I think that's the second or third time I've done that. Lack of sleep. Sorry for posting useless crap.

Will I lose all "my documents" if I do a fresh install of windows xp instead of a repair? I have the option to do it without formatting the drive and it says it will leave everything intact....?...?

By reinstalling but not formating, your documents and settings should transfer over without any loss or problem.

Hopefully you have good backups anyway. You should always back up your importent documents and files, at least once a week. I know that most people don't, and if they transfer without a hitch or if you end up losing some of them, consider it as a wakeup call and start backing up your important files and documents on a regular basis just for situations like this.

na, no backups over here. I am thinking i am going to go ahead and boot up knoppix and move my files over to my server. I cannot slave a harddrive because it is a laptop.

When the reboot dialog window comes up, go to: Start > Run, then type 'Shutdown -a' That will stop the reboot process, and you can download the sasser removal tool here: http://www.sarc.com/avcenter/venc/da...oval.tool.html

You should be perfectly OK with a re-install of Windows, all your personal files will remain untouched and if they are in your "My Documents" folder they will be in the same place afterwards.

Just dont select any Format, Partitioning or File System change (NTFS/FAT32) when you are going through the process!

There is a way to repair the lsass error without doing a reinstall.

The simplest way is to remove the hard drive and place it in another machine.
Scan it for virus/worms just to be sure.
Open the System Volume Information folder on the drive containing the broken Windows.
Browse down to the next to newest folder and then to the snap shot that is as new as you trust.
In hear you will find a set of registry files that can be copied into the system32/config folder to replace the corrupted registry.

This can also be accoplished from a linux boot disk as well as (I think) from the repair console (if you know the password)

If further details are needed let me know.

The thread is two weeks old, as witnessed by the flashing date in the header of each response..... His report is now way overdue.... ;)

While your response may be correct it is not very precise.... I'm pretty good with computers but I'm unsure as to where your instructions would lead..... Try to be precise. If you can, go through the process as you write it out so that you are sure you are giving accurate and intuitive information to the readers..... It'll make you more helpful to others.

I am still having the problem.... na Just kidding.....
