Microsoft has announced the release of out-of-band updates to address issues with Active Directory authentication issues. These authentication issues occurred as a result of the May 2022 Patch Tuesday updates on domain controllers. Microsoft has worked on issuing an emergency update for Windows AD authentication issues since May 12th.
This issue was originally brought to light after several Windows administrators started sharing reports on Reddit of some policies failing after installing this month’s security updates.
Microsoft explained that “After installing updates released May 10, 2022 on your domain controllers, you might see authentication failures on the server or client for services such as Network Policy Server (NPS), Routing and Remote access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP).”
The OOB Windows Updates released today (05/19/2022) are available only via the Microsoft Update Catalog and will not be offered or installed through Windows Update. In the event you are experiencing any issues after the May 2022 Patch Tuesday, it is important that you install the emergency update for Windows AD Authentication issues.
The following cumulative updates have been released for installation on Domain Controllers:
- Windows Server 2022: KB5015013
- Windows Server, version 20H2: KB5015020
- Windows Server 2019: KB5015018
- Windows Server 2016: KB5015019
Microsoft also released standalone updates:
- Windows Server 2012 R2: KB5014986
- Windows Server 2012: KB5014991
- Windows Server 2008 R2 SP1: KB5014987
- Windows Server 2008 SP2: KB5014990
