Cumulative updates that are supposed to refine the experience on Windows devices continue to cause all sorts of problems, and this time Windows Server is the platform that is impacted.
Microsoft recently explained that users who have the Late January 2022 Cumulative Updates installed on their devices may have difficulty with DNS resolution on Windows Server 2019. Keep in mind that client versions of Windows are not affected , because the problem only exists on Windows Server. .
“After installing updates released January 25, 2022 (KB5009616) and later affected versions of Windows Server running the DNS server role, DNS stub zones may not load correctly, which may cause the DNS name resolution failed. A stub zone is a copy of a Domain Name System (DNS) zone that contains only resource records that identify the DNS servers in that zone,” Microsoft explains.
A full patch is already available
Microsoft recently announced that a fix is already available, but on the other hand, it comes in the form of a known rollback issue. This means the devices don’t come with a downloadable patch, with Microsoft explaining that the patch requires two Group Policy downloads.
You can find the two policies that need to be deployed on this page.
“This issue is resolved using Known Issues Rollback (KIR). This KIR will not automatically propagate to devices. Devices that have installed an affected update and experienced this issue can resolve it by installing and configuring two (2) special Group Policies listed below. For more information on deploying and configuring these special Group Policies, please see How to Use Group Policy to Deploy a Known Issue Restore » , explained the company.
Microsoft insists that IT administrators should download and enable both policies on their Windows Server 2019 devices in order to resolve the issue.
