Symptoms

Assume that one of the following conditions is true:

In either of these situations, the Lsass.exe process crashes, and then the computer restarts. Additionally, an event that resembles the following is written to the Application log:

Note This event identifies NTDSATQ.dll as the faulting module.

Cause

This issue occurs because the computer does not handle the incoming LDAP requests correctly in certain situations under heavy LDAP traffic. This causes the failure in the NTDSATQ.dll module that crashes the Lsass.exe process.
