Security News > 2022 > March > Microsoft: Windows domain controller restarts caused by LSASS crashes

Microsoft shared info on a now-fixed known issue leading to Local Security Authority Subsystem Service crashes and Windows Server domain controller.

As Microsoft explains in a new entry added to the Window Health dashboard, unexpected restarts are triggered on Windows Servers domain controllers after installing updates released during the January 2021 Patch Tuesday.

Microsoft addressed the LSASS crash issue in out-of-band updates released in mid-January 17 [1, 2] to fix numerous other critical bugs introduced during the January 2022 Patch Tuesday, including Hyper-V no longer starting, L2TP VPN connections failing, and ReFS volumes becoming inaccessible.

While domain controllers entering boot loop issues were also mentioned when the out-of-band updates were released, Microsoft did not share any information on what was causing them.

Redmond recommends installing the latest security updates released on February 8 to address the issue and prevent your Windows domain controllers from randomly restarting.

The January out-of-band updates are available for download through the Microsoft Update Catalog or Windows Update as optional updates.
