The March 2024 Windows Server updates are causing some domain controllers to crash and restart, according to widespread reports from Windows administrators.
Affected servers are freezing and rebooting because of a Local Security Authority Subsystem Service process memory leak introduced with the March 2024 cumulative updates for Windows Server 2016 and Windows Server 2022.
As many admins have warned, after installing the KB5035855 and KB5035857 Windows Server updates released this Patch Tuesday, domain controllers with the latest updates would crash and reboot due to increasing LSASS memory usage.
Until Microsoft officially acknowledges this memory leak issue, admins are advised to uninstall the buggy Windows Server updates from their domain controllers.
Microsoft addressed another LSASS memory leak affecting domain controllers in December 2022, when affected servers would freeze and restart after installing Windows Server updates released during the November 2022 Patch Tuesday.
In March 2022, Microsoft fixed one more LSASS crash, causing unexpected Windows Server domain controller reboots.
