About this tag
LSASS crashes on Windows Server domain controllers have been a recurring issue, particularly following the April 2026 security updates. Multiple reports link these crashes to reboot loops affecting domain controllers, especially in environments using Privileged Access Management (PAM). The crashes can cause authentication failures, broken directory services, and widespread outages. Microsoft released an out-of-band fix to address the restart-loop problem tied to LSASS crashes. The issue spans Windows Server 2016 through 2025 and coincides with a Kerberos hardening change, making the April 2026 update cycle particularly challenging for enterprise identity teams. Administrators should monitor for LSASS crash patterns and apply the OOB fix to mitigate disruptions.
