SYMPTOMS

Assume that you type an invalid IPv6 subnet mask in the Active Directory Sites and Services snap-in on a Windows Server 2008 R2-based domain controller. In this situation, the Local Security Authority Subsystem Service (Lsass.exe) process crashes.

After some time, the invalid IPv6 subnet mask is replicated to all domain controllers in the environment. Therefore, the Lsass.exe process on all domain controllers crashes. When this issue occurs, the domain controllers restart repeatedly.

CAUSE

This issue occurs because of an access violation in the Lsass.exe process when the subnet information is updated by the Net Logon service.
