If your Windows domain controllers have been crashing since a security update was installed earlier this month, there’s no longer any need to speculate why: Microsoft has admitted it introduced a memory leak in its March patches and fixed the issue.

Microsoft has since confirmed the issue is to do with the Local Security Authority Subsystem Service process on Windows Server 2012 R2 (no longer under support), 2016, 2019 and 2022.
