You can download the Hiren disk and boot up your computer from it and run the malwarebytes program. If you get a stupid message saying that it will not work, ignore and run it.

Hi,

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.

This can happen after installing an antivirus. You might need to go into safe mode by hitting I believe F8 key after turning on computer, while you're still in the black screen and then uninstalling antivirus. You can also try the following link on repairing windows http://michaelstevenstech.com/XPrepairinstall.htm

You have unfortunately picked up a copy of the old lsass virus. This was someone's idea of a funny virus in as much as it would just keep giving you the countdown and shutting your computer down. If you have an anti-virus program installed on your computer what you can do is boot your computer into safe mode (this can be accomplished by pressing F8 during your computers bootup. On the menu that appears choose to boot in safe mode), and then running a complete scan on your entire hard drive. By booting the computer in Safe Mode all of the extra programs that normally load will not do so. Once your scan is complete, and you have deleted all of the infected files, you should then be able to boot your computer into the regular Windows program.

Thank you for the opportunity to assist you in resolving your issue. Should you need further information or assistance please do not hesitate to let us know.

How to fix lsass.exe error


hello

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.
1.
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.
2.
Press ENTER when you see the message To setup Windows XP now, and then press ENTER displayed on the Welcome to Setup screen.
3.
Do not choose the option to press R to use the Recovery Console.
4.
In the Windows XP Licensing Agreement, press F8 to agree to the license agreement.
5.
Make sure that your current installation of Windows XP is selected in the box, and then press R to repair Windows XP.
6.
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.

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

I have a lsass.exe error message and netbook keeps restarting, it wont boot in safe mode or anything and I have no cd drive either. Please help...


lsass.exe is certainly a virus issue, the actual process isnt really a virus but viruses hijack the process for their own nefarious reasons.
You only have two options really, 1) use a boot disk antivirus (search google for avg boot cd) and then use the restore disks to try and repair the system file (copy the one off the restore disk to replace the corrupt one on your system)
2) Use your restore disks / another installation disk to build a new operating system.

Just remember if you have data on the drive to take it out to get your data off first. Personally I'd take your drive out and put a new drive in, then build a new OS on the new drive, nice clean and fast, then put your data onto it.

Windows xp won`t boot up. Get error messages services.exe and Lsass.exe and screen goes black...thank you....


Unfortunately, Lsass.exe is the security policy manager for Windows XP. You only options will be to try and press F8, and choose "Last Known Good Configuration." If that doesn't work, you will need a Windows XP CD. Enter that into the drive and boot to the CD. Go to Repair (not Recover Console). This will rebuild Windows XP, and keep your data intact.

Good luck, and I hope this helps somewhat!

Compaq Presario V2000 - lsasse.exe error


That little app is a major factor in the security of your system. You should boot from the XP CD and attempt to repair your current XP installation to rremedy the problem. It can lead to problems connecting to other computers on occasion, but more frequently it can cause problems accessing files on your hard disk.

Lsass.exe-Unable to locae component


Boot from your WinXP CD and repair your existing installation. That is the component that controls security on your computer. When done with the repair and you can boot into your operating system again, you should do a full virus scan on the computer since there are several viruses that can cause this problem.

Pc does not go beyond Lsass.exe application error


Try getting into safe mode, by taping the f7 or f8 key before it boots. Once in safe mode we can do a restore to the last restore point, and go from there. If you can't get into safe mode, let me know and we will go into the bios, set the machine to boot from the dvd drive and use your xp disk to boot her up, this method id too much to post here, let me know and we will take it up only if needed. Also try this, turn off any user accounts that the computer has installed other than your administrator account, and let me know what happens

Boot sequence manual


When you hit the power button on your computer a whole lot of stuff happens. We call this the boot process. In the days when I first started using computers there was literally a "boot disk", a floppy (5.25" not a 3.5") disk that told the system where to go and what to do so that the operating system would start up. Since then the boot sequence has become somewhat more complicated. So let me take you thru the steps the computer takes to get started. For my example I'm going to use a Windows XP system.
  1. First is the POST, this stands for Power On Self Test, for the computer. This process tests memory as well as a number of other subsystems. You can usually monitor this as it runs each test. After that is complete the system will run POST for any device that has a BIOS (Basic Input-Output System). An AGP has its own BIOS, as do some network cards and various other devices.
  2. Once the POST is complete and the BIOS is sure that everything is working properly, the BIOS will then attempt to read the MBR (Master Boot Record). This is the first sector of the first hard drive (called the Master or HD0). When the MBR takes over it means that Windows is now in control.
  3. The MBR looks at the BOOT SECTOR (the first sector of the active partition). That is where NTLDR is located, NTLDR is the BOOT LOADER for Windows XP. NTLDR will allow memory addressing, initiate the file system, read the boot.ini and load the boot menu. NTLDR has to be in the root of the active partition as do NTDETECT.COM, BOOT.INI, BOOTSECT.DOS (for multi-OS booting) and NTBOOTDD.SYS (if you have SCSI adapters)
  4. Once XP is selected from the Boot Menu, NTLDR will run NTDETECT.COM, BOOT.INI and BOOTSECT.DOS to get the proper OS selected and loaded. The system starts in 16-bit real mode and then moves into 32-bit protected mode.
  5. NTLDR will then load NTOSKRNL.EXE and HAL.DLL. Effectively, these two files are windows XP. They must be located in %SystemRoot%System32.
  6. NTLDR reads the registry, chooses a hardware profile and authorizes device drivers, in that exact order.
  7. At this point NTOSKRNL.EXE takes over. It starts WINLOGON.EXE that in turn starts LSASS.EXE, this is the program that display the Logon screen so that you can logon.

Turn off problem


If you have (L)lsass.exe, that is a windows executable file, if you have Isass orisass.exe, then you have a trojan, run your antispyware and antivirus programme using safe mode (press F8 on boot up) to enter safe mode. Also you must turn off system restore before you run the virus removal, then turn it back on again.
