SYMPTOMS

On a computer that is running Windows 7 or Windows Server 2008 R2, you use Credential Manager to store user credentials. When multiple Kerberos authentication requests are made at the same time, the computer restarts.

This issue usually occurs on a computer when multiple CredMan entries are created for the same user in Credential Manager.

CAUSE

The issue occurs because of an access violation in the Local Security Authority Subsystem Service (Lsass.exe).
