Microsoft has confirmed that the April 2026 security update (KB5082063) can cause LSASS crashes and repeated restarts on non-Global Catalog Windows domain controllers in environments using Privileged Access Management (PAM), potentially rendering authentication and directory services unavailable; affected platforms include multiple Windows Server releases (Windows Server 2025, 2022, 23H2, 2019, 2016) and Microsoft advises contacting Support for mitigation while a fix is worked on.
