Windows admins are seeing authentication failures on the server and client side after installing the latest Patch Tuesday updates.
Following the deployment of its latest round of Patch Tuesday updates, Microsoft is currently investigating a known issue that leads to authentication failures for a number of Windows services. According to BleepingComputer, the software giant began looking into these issues after Windows admins began sharing reports of certain policies failing after installing its May 2022 Patch Tuesday updates. These admins reported that after installing the updates they began seeing the following error message: “Authentication failed due to a user credentials mismatch. Either the user name provided does not map to an existing account or the password was incorrect.”
While this issue impacts client and server Windows platforms and systems including those running Windows 11 and Windows Server 2022, Microsoft says that it is only triggered after updates are installed on servers that are being used as domain controllers.
