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 cumulative security update contains improvements that are part of update KB5012670 (released April 12, 2022) and 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.

  • After installing the January 2022 Windows update or a later Windows update on the Primary Domain Controller emulator (PDCe), listing or modifying name suffixes routing by using Netdom.exe or "Active Directory Domains and Trusts" snap-in may fail and you receive the following error message: "Insufficient system resources exist to complete the requested service."

  • 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 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.

How to get this update

Before installing this update

We strongly recommend that you install the latest servicing stack update (SSU) for your operating system before you install the latest Rollup. SSUs improve the reliability of the update process to mitigate potential issues while installing the Rollup and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

If you use Windows Update, the latest SSU (KB5014025) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog
