"The Windows Server 2025 OOB update (KB5091157) addresses both the installation failure issue and the domain controller restart issue, according to Microsoft."
"In addition to the LSASS crashes and the installation error in KB5082063, Microsoft also warned that some Windows Server 2025 devices boot into BitLocker recovery mode after installing the update."
Microsoft has issued emergency updates for various Windows Server versions due to problems stemming from the April 2026 Patch Tuesday updates. Domain controllers experienced reboot loops caused by crashes of the Local Security Authority Subsystem Service (LSASS), leading to unavailable authentication services. New domain controllers also faced issues if authentication requests were processed prematurely. The OOB update KB5091157 resolves both the installation failure and domain controller restart issues for Windows Server 2025, while other updates address only the restart issue.
