Data Recovery Software Help For Windows, Mac , Linux Systems

LSASS (Local Security Authority Subsystem Service) is a Microsoft Windows process that serves as the Local Security Authentication Server. The file performs tasks, like enforcing system security policy, handling password changes, verifying users logging onto Windows system or server, creating access tokens, and writing to the Windows Security Log. When you try to access the computer, the file checks the provided identity information for validity. If you forcibly terminate lsass.exe process, you lose all accounts. At times, a lsass.exe system or application error makes the computer unusable to operate. You computer might enter a reboot loop without permitting you to access the stored data. If all the recommended solutions fail, you might need to perform a clean reinstall of Windows. Since it deletes all the data, you need to use to restore it using an updated backup or a powerful Data Recovery utility.

For instance, you might come across the below symtoms with your Windows based computer:

• Error “The system process ‘C:\WINDOWS\system32\lsass.exe’ terminated unexpectedly with status code -<status_code>. The system will now shut down and restart.”

• An lsass.exe error causing system to reboot continuously

• You try to change the password but fails with an lsass.exe error

Cause

A Windows computer exhibits the above behavior in any of the below conditions:

• Authenticated user group doesn’t have required Apply Policy and Read Permission in order to access GPO applied on domain system.

• Your computer cannot get user authentication token from server.

• Your computer is infected from Sasser worm, , corrupt or missing configuration file or registry entry

Solution

You need to apply the following measures to isolate the described system behavior:

• In case of permission issues, you should grant the required permissions to the default domain policy

• As your computer starts after reboot, immediately click Start → Run and then type shutdown -a to prevent it from restarting

• Start the computer in Safe mode and scan it using an up-to-date antivirus program

• Install all the Windows updates available

• If the problem persists, repair Windows installation or perform a clean Windows reinstall

Clean Windows reinstall causes data loss, thereby compelling you to restore from backup. If no suitable backup is present, use a data recovery software to restore it. Data recovery applications serve as advanced and safe utilities using high-end scanning algorithms to locate and restore missing data. These tools are perfect partition recovery software.
