Microsoft has released updates for various versions of Windows Server that resolve issues encountered after installing the May 2022 security updates.
Updates resolve authentication issues and Microsoft Store app installation issues. Released updates are not distributed through Windows Update, but only available as manual downloads from the Microsoft Update Catalog website.
Authentication issues
The first issue was encountered after installing the May 2022 Updates on domain controllers. Some administrators have noted an increase in server or client authentication failures for services including Network Policy Server (NPS), Routing and Remote Access Service (RRAS), Radius, Extensible Authentication Protocol (EAP), and Protected Extensible Authentication Protocol (PEAP) .
Microsoft discovered that the issue affects how domain controllers handle certificate mapping to computer accounts. The company released a workaround for the issue shortly after confirming it on its Docs website. Administrators must manually map certificates to machine accounts in Active Directory to resolve the issue. While other mitigations have been released, all “could reduce or disable security hardening” and were therefore not recommended.
Microsoft Store app installation failures
On some devices, installing Microsoft Store apps may fail with error code 0xC002001B after installing May 2022 updates. Some installed apps may also fail to open.
According to Microsoft, the issue occurred on devices with Control-flow Enforcement Technology processors.
Additional details are available on the Microsoft Docs website.
Out-of-band updates are available
Microsoft has released out-of-band updates for affected Windows Server versions. Cumulative updates are available for Windows Server versions 2016, 2019, 2022 and 20H2:
These can be installed directly as they are cumulative in nature and include previous updates that may not have been released yet.
Windows Server 2008 R2 SP1, 2008 SP2, 2012, and 2012 R2 versions can be updated using standalone updates instead:
Microsoft notes that the installation of standalone updates differs depending on whether machines have monthly updates or security-only updates installed.
On machines with security-only updates, standalone updates can be installed directly. On monthly cumulative updates, it is necessary to install the standalone update and the monthly cumulative update released on May 10, 2022.
A restart may be required to complete the update installation.
Now you: Have you installed the May 2022 Updates yet?
