The Register revealed on Monday that Microsoft had admitted to having released a memory leak in its March patches, but that the problem had been resolved.
People had been guessing about their domain controls crashing for days. Additionally, Windows Server servers were stopping and restarting, according to sysadmins.
With reference to the “Local Security Authority Subsystem Service process on Windows Server 2012 R2 (no longer under support), 2016, 2019, and 2022,” the tech behemoth confirmed the problem.
The issue arises “when on-premises and cloud-based Active Directory Domain Controllers service Kerberos authentication requests,” according to articles from Microsoft outlining known problems with its Server OS.
Extreme memory leaks have the potential to cause LSASS to fail, which would then force an unplanned reboot of the underlying domain controllers, according to Redmond.
