Microsoft Emergency Update Fix AD Authentication Issues

Share post:

Microsoft has released emergency updates to address authentication issues with Active Directory (AD).

After installing the May 2022 patch Tuesday updates, authentication issues occurred that led to authentication errors on some Windows services.

The OBB Windows updates can only be accessed via the Microsoft Update Catalog and are not offered via Windows Update.

Cumulative updates for installation on Domain Controllers include KB5015013 for Windows Server 2022; KB5015020 for Windows Server version 20H2; KB5015018 for Windows Server 2019; and KB5015019 for Windows Server 2016.

Other standalone updates released by Microsoft include KB5014986 for Windows Server 2012 R2, KB5014991 for Windows Server 2012, KB5014987 for Windows Server 2008 R2 SP1, and KB5014990 for Windows Server 2008 SP2.

Users can manually import the updates into the Windows Server Update Service (WSUS) and Microsoft Endpoint Configuration Manager.

“If you are using security updates for these versions of Windows Server, you only need to install these updates for May. If you are using Monthly Rollup updates, you will need to install both the standalone update listed above and the Monthly Rollups released on May 10, 2022,” Microsoft clarified.
