How to fix lsass.exe error


for a simple fix, try this -- if not go to the next step

From your post, I understand that you cannot manage to boot or logon into Windows.
lsass.exe is a favorite target of viruses, and it's likely that a virus has destroyed lsass.exe while trying to infect your machine.
If you can boot into Safe mode (F8 during the boot), restore your system to an earlier system restore point. Then scan your disk using several anti-virus programs.
If you can't boot into Safe mode, try to boot into the Last Known Good Configuration (using F8).

If that also doesn't work, you should --follow these steps

How do you perform a reinstallation of Windows XP, sometimes called a repair installation?
Configure your computer to start from the CD-ROM drive. For more information about how to do this, refer to your computer's documentation or contact your computer manufacturer. Then insert your Windows XP Setup CD, and restart your computer.
When the Press any key to boot from CD message is displayed on your screen, press a key to start your computer from the Windows XP CD.
Press ENTER when you see the message To setup Windows XP now, and then press ENTER displayed on the Welcome to Setup screen.
Do not choose the option to press R to use the Recovery Console.
In the Windows XP Licensing Agreement, press F8 to agree to the license agreement.
Make sure that your current installation of Windows XP is selected in the box, and then press R to repair Windows XP.
Follow the instructions on the screen to complete Setup.

If you still have the lsass.exe error and your Windows keep restarting or you can't even open Windows anymore, its because the error has a small problem in the lsass.exe file itself. This is not a hard issue to rectify . In fact, it isn't really that hard to fix.

To get this problem fixed, you need to repair the lsass.exe file by getting a PC repair program. This program will scan your computer to detect the error and to repair it. Also, it will allow you to recover files that are missing and it will repair or delete the files that are causing problems to your computer.
This PC Repair Program will work- The PC REPAIRING PROGRAM works by an automated process. First of all you will have to start the scanning process while using this program. Once the scan is done, you will get a list of troubleshooting files.
It will also show the lsass.exe error file. Once you've spotted this file, you simply select the category and you press the repair problem button and it will start to repair the lsass.exe file. Once the repairs are done, you simply restart your PC and it's fixed.
This program will not damage any of your software programs already installed. It even allows you to create a backup file from your hard drive.
This software tool will also help you to detect other problems like viruses, worms, cookies and even pop-ups. This way, your computer will be cleaner and faster then before.

So, to repair the lsass.exe error you will need to get the Registry Easy program so you can start a scan, detect the lsass.exe file it's problem and start repairing it.

Want to start up Windows again without any problems? Today? Right now? Visit: Regcure.

lsass.exe is probably located in the folder C:\Windows\System32. Known file sizes on Windows XP are 7k-33k bytes long .space.gif
It is a Windows core system file. The program is not visible. File lsass.exe is a trustworthy file from Microsoft. Program listens for or sends data on open ports to LAN or Internet. Therefore the technical security rating is 9% dangerous.

lsass.exe is harmless and if u kill it, it's likely to reboot or revert to welcome screen. two famous viruses are lsass.exe begining with an "I" or ending in triple "s"

lsass is a legitimate Windows object for user authentication but it is vulnerable to the sasser virus and can be HiJacked. Someone please clean up this place as at least half of the entries are worthless. it may be a trojan (form of virus) named SASSER

please rate me with 4 thimbs up

Lsass.exe Insufficient resources to complete API

In safe mode it does the same reboot reboot thing? Computer messages are not really reliable as far as fault tracing is concerned. The message given is a close as the PC can come to the right one.It sound as though there is a problem reading the hard drive. Try booting from a bootable CDor flash drive if you don't have a floppy drive, and see it if does the same.Can you get into the BIOS setup by pressing delete on bootup?

Running WinXP (has service pack 3) When I turn on my laptop, I get an "lsass.exe" application error. When I reboot and try to run in safe mode, the same error pops up. Ran a diagnostic test in and received...

Hi, this might help you:

try to use system repair to go back if able to.
or try to deinstall the service pack.

also an option but not a guaranteed solution:
maybe due to long period of use your pc needs a cleanup, so i can advice you a freeware like ccleaner.
go to, doznload it at 'downloads'from (their official download link), and check it out. could be that it just a bit of a mess that slows every pc down or gives you problems once in a while....

I hope this is useful, and greets.

Lsass.exe system error An invlid parameter was


It seems your system file got crashed which you need to recover using Recover Disc.

Take any Windows XP installtion disc and boot the system from CD.

After all the scanning of Hardware it ask you want to install fresh copy of windows or you just want to repair it.

Choose Automatic repair, it will run thru the wizard as similar to windows intallation. Only difference it will just repair the crrupted system files without user files loosing.

So thats all you need to make it work fine.

HP - Compaq 6310P Laptop that Is giving an Isass.exe system error

As you may know, lsass is; Local Security Authentication Server. ANY OF THESE THINGS CAN RESULT IN AN UNUSABLE SYSTEM! So don't try them if you aren't able to re-install your operating system without trashing it (Over top should work), if there's any information not backed up that you can't lose, or aren't prepared for the worst, because that's what usually happens, right? :^D TAKE IT TO SOMEONE IF ANY OF THESE THINGS APPLY TO YOU.

Although you shouldn't have any problems with these simple remedies, I don't want to be responsible if it does!

The trojan you found and removed has corrupted some registry settings.

If you have a known good configuration, you can "go back". OR you can try running a registry cleaner on it.

You can also try going into "Services" and killing it, which should bring up your Welcome screen and reboot. All of your usernames and passwords may be gone though! And you'll have to start over.
