Back in July of 2013 I faced an issue with my Exchange 2013 Server running on Microsoft Server 2012.
Our server would unexpectedly reboot ( — chuckles — aren’t all reboots without notice unexpected).
The message I kept running into was regarding a faulting application which caused the reboot was the local security authority subsystem service (LSASS).
What’s known about the lsass.exe is that if it is stopped it will result in causing your system to reboot. LSASS also handles the validation of user logins on a Windows Computer / Server.
As I mentioned in my previous blog post:
There was an event message in the system event log of:
The process wininit.exe has initiated the restart of computer EXSERVER on behalf of user for the following reason: No title for this reason could be found
Reason Code: 0×50006
Shutdown Type: restart
Comment: The system process ‘C:Windows\system32\lsass.exe‘ terminated unexpectedly with status code 255. The system will now shut down and restart.
Later I found in the application log event 1000 application error:
Faulting application name: lsass.exe, version: 6.2.9200.16384, time stamp: 0x50108ab2

Faulting package-relative application ID:
The Exception code: 0xc0000409 only tells me that the application experienced an event it could not handle and crashed causing windows to reboot.
Months of searching forums and discussing this with systems administrators from all over the word we all determined that there was no clear regarding how to handle this issue.
Today I got an email regarding a solution for this problem:
There seems to be a solution in the form of roll-up update from Microsoft to address this along with other issues which are also listed in the following KB articles:
