14 DAY TRIAL // The cumulative updates that are supposed to refine the experience on Windows devices continue to cause all kinds of problems, and this time, Windows Server is the platform that’s impacted.
Microsoft explained recently that users who installed the late-January 2022 cumulative updates on their devices might end up struggling with DNS resolution on Windows Server 2019. Keep in mind that the client versions of Windows are not affected, as the issue exists only on Windows Server.
“After installing updates released January 25, 2022 ( KB5009616) and later on affected versions of Windows Server running the DNS Server role, DNS stub zones might not load correctly, which might cause DNS name resolution to fail. A stub zone is a copy of a Domain Name System (DNS) zone that contains only resource records that identify the DNS servers for that zone,” Microsoft explains
A full fix is already available
Microsoft announced recently that a fix is already available, though on the other hand, it comes in the form of a Known Issue Rollback. This means that devices aren’t provided with a downloadable patch, with Microsoft explaining the fix requires two Group Policy downloads.
You can find the two policies that must be deployed on this page.
“This issue is resolved using Known Issue Rollback (KIR). This KIR will not propagate to devices automatically. Devices that have installed an affected update and encountered this issue can resolve it by installing and configuring two (2) special Group Policies listed below. For information on deploying and configuring these special Group Policies, please see How to use Group Policy to deploy a Known Issue Rollback,” the company explained.
Microsoft insists that IT admins need to download and enable both policies on their Windows Server 2019 devices in order to resolve the glitch.
