May 10, 2022—KB5014001 (Security-only update)

Summary

Learn more about this security update, including improvements, any known issues, and how to get the update.

IMPORTANT Windows 8.1 and Windows Server 2012 R2 have reached the end of mainstream support and are now in extended support. Starting in July 2020, there will no longer be optional, non-security releases (known as “C” releases) for this operating system. Operating systems in extended support have only cumulative monthly security updates (known as the “B” or Update Tuesday release).For information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article. To view other notes and messages, see the Windows 8.1 and Windows Server 2012 R2 update history home page.

Improvements

This security-only update includes new improvements for the following issues:

  • The Key Distribution Center (KDC) code incorrectly returns error message KDC_ERR_TGT_REVOKED during Domain Controller shutdown.
  • The Primary Domain Controller (PDC) for the root domain incorrectly logs warning and error events in the System log when trying to scan outbound-only trusts.
    For more information about the resolved security vulnerabilities, please refer to the new Security Update Guide website and the May 2022 Security Updates.

Known issues in this update

Symptom Next step
Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege. Do one of the following:
  • Perform the operation from a process that has administrator privilege.
  • Perform the operation from a node that doesn’t have CSV ownership.
    Microsoft is working on a resolution and will provide an update in an upcoming release.
    After installing this update on your Windows Server 2012 R2 servers used as 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 issue affects how the domain controller manages the mapping of certificates to machine accounts. This issue only affects servers that are used as domain controllers and intermediary application servers which authenticate to domain controllers; it does not affect client Windows devices.| Install update KB5014986 on Windows Server 2012 R2 servers used as domain controllers and intermediary application servers which authenticate to domain controllers.
