Security News > 2022 > March > Microsoft: Recent Windows Server updates cause DNS issues

Microsoft has addressed a new known issue causing DNS stub zones loading failures that could lead to DNS resolution issues on Windows Server 2019 systems.

DNS stub zones are copies of DNS zones containing resource records needed to determine the authoritative DNS servers for a specific zone and resolve names between separate DNS namespaces.

"After installing updates released January 25, 2022 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," Microsoft explained.

To fix the DNS issues on enterprise-managed devices where the buggy Window Server updates have been installed, the admins will have to install and configure two group policies.

Microsoft has previously fixed multiple issues linked to the Windows January updates, including a Bluetooth issue causing Windows blue screens, Windows domain controller restarts caused by LSASS crashes, Netlogon issues, and a Windows Active Directory bug.

Redmond also released out-of-band emergency updates to address issues caused by the January 2022 Patch Tuesday updates.
