As is usually the case, Microsoft’s monthly security updates are causing issues outside the fixes that they bring. Following the release of updates (KB5021249 and KB5021237) on December 2022 Patch Tuesday, Microsoft is confirming new issues caused by that updates in Windows Server 2022 and Windows Server 2019.
Specifically, there is a problem with network adapters and NICs in Hyper-V. Microsoft has been quick in solving this issue and is now sending out-of-band (OOB) updates as a fix. On Windows Server 2022, users can install KB5022553, while for Server 2019, KB5022554 is the patch.
Microsoft provides the following changelog to confirm the patches:
