LSASS Crashing, CNF Objects May Be the Cause

What Happens and How Do I Know if I’m Affected?

When CNF mangled NTDS settings objects are created, the Lsass.exe process may crash and unexpectedly reboot one or more domain controllers. So there is a pretty good chance you’ll know about it. You may not know the root cause of the crash. More specifically though you’ll see the following events in the Application Log which you can look for.
