Security News > 2022 > May > Microsoft emergency updates fix Windows AD authentication issues
Microsoft has released emergency out-of-band updates to address Active Directory authentication issues after installing Windows Updates issued during the May 2022 Patch Tuesday on domain controllers.
"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, Routing and Remote access Service, Radius, Extensible Authentication Protocol, and Protected Extensible Authentication Protocol," Microsoft explained.
The OOB Windows updates released today are available only via the Microsoft Update Catalog and will not be offered through Windows Update.
These updates can be manually imported into Windows Server Update Services and Microsoft Endpoint Configuration Manager.
"If you are using security only updates for these versions of Windows Server, you only need to install these updates for the month of May," Microsoft added.
In November 2021, Microsoft released another round of out-of-band updates to address an issue causing Windows Server authentication failures related to Kerberos delegation scenarios impacting domain controllers.
