Recent Windows Server Updates Cause DNS Errors

Microsoft has just fixed an issue that caused DNS stub zone loading errors that could lead to DNS resolution issues on Windows Server 2019 systems.

A DNS zone stub is a copy of a DNS zone containing the resource records needed to determine the authoritative DNS server for a particular zone and to resolve domain names between distinct DNS name zones.

According to information published by Microsoft on the Windows health monitoring page, users will encounter this problem after installing updates released after January 25, 2022.

Two other Windows Server updates that can cause DNS issues are KB5010427 (released February 15) and KB5011551 (released March 22).

Microsoft fixed this issue through the Known Issue Rollback (KIR) feature. However, it does not automatically propagate to affected devices.
