Microsoft has addressed an LSASS memory leak issue on some domain controllers that led to freezes and restarts after installing Windows Server updates released during last month's Patch Tuesday.

LSASS enforces Windows security policies and handles user logins.

If it crashes, logged-in users immediately lose access to Windows accounts on the machine after being shown a restart error followed by a system reboot.

Redmond acknowledged the issue in late November, two weeks after the updates were issued, saying that it affects multiple Windows Server versions, including Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2 SP1, and Windows Server 2008 SP2. At the time, the company also added that out-of-band Windows updates pushed out to address authentication problems on Windows domain controllers might also be affected.

In March, Microsoft fixed another known issue leading to Windows Server domain controller reboots because of LSASS crashes.

In November, Redmond issued emergency out-of-band updates to fix domain controller sign-in failures and other auth problems also caused by last month's Patch Tuesday Windows updates.
