Microsoft has recalled the January Windows Server cumulative updates after critical bugs caused domain controllers to reboot, Hyper-V to not work, and ReFS volume systems to become unavailable.
Tuesday, Microsoft released the January 2022 Patch Tuesday updates for Windows Server that includes numerous security updates and bug fixes.
These updates are KB5009624 for Windows Server 2012 R2, KB5009557 for Windows Server 2019, and KB5009555 for Windows Server 2022.
Windows Server updates Recalled and Republished
Soon after Microsoft released this week’s Windows Server updates, admins who installed them began reporting that they encountered numerous severe issues.
These issues included domain controllers going through an endless reboot loop, ReFS volumes becoming inaccessible and showing as RAW file systems, and Hyper-V no longer starting on servers.
Apparently, Microsoft recalled the windows server updates and then they re-issued the new patch yesterday. Microsoft has also created two new known issues in the Windows Message Center with more information.
“After installing KB5009557 on domain controllers (DCs), affected versions of Windows Servers might restart unexpectedly. Note: On Windows Server 2016 and later, you are more likely to be affected when DCs are using Shadow Principals in Enhanced Security Admin Environment (ESAE) or environments with Privileged Identity Management (PIM),” Microsoft explains regarding the domain controller reboots.
