Server 2012 stuck in a reboot loop - lsass.exe failed

  • 772

My Server 2012 server boots up fine and the login screen is visible (from a local console). Password entry works but attempting to submit the password - either by clicking the arrow or pressing the Enter key - is futile. Nothing happens. After about 1 minute the computer immediately restarts - no blue screen or error message.

I can boot into Safe Mode and looking at the System event log I can see that a system-initiated restart has taken place. The Information message (Event ID: 1074) is as follows:

The process wininit.exe has initiated the restart of computer <computer name> on behalf of user  for the following reason: No title for this reason could be found
 Reason Code: 0x50006
 Shutdown Type: restart
 Comment: The system process 'C:\Windows\system32\lsass.exe' terminated unexpectedly with status code -1073740791.  The system will now shut down and restart.

I have tried to find the meaning of this error code online but it seems that no-one else has experienced this specific error.

What can I do to save my server?

    This error is caused by LastPass. The login hooks used by LastPass seem to be incompatible with Server variants of Windows - causing lsass.exe to crash.

    Note the following related error message (Event ID: 1000) in the Application event log:

    Faulting application name: lsass.exe, version: 6.3.9600.17415, time stamp: 0x545042fe

    Because the services required for uninstalling the LastPass application are not available in Safe Mode - the easiest way to resolve this issue is to rename the lplogin.dll to lplogin.dll.bak (thus preventing Windows from loading LastPass at boot-time). Once you have successfully booted into normal Windows - you can simply uninstall the LastPass application.
