Microsoft confirms recent Windows updates cause problems establishing Netlogon secure channel connections
Microsoft has issued a warning to users of various versions of Windows Server that a recent update is causing problems with Netlogon connections.
Affecting Windows Server 2022, 2019, 2012 R2, 2012, 2008 R2 SP1 and 2008 SP2, the problem means that some applications and appliances on domain controllers may be unable to establish a Netlogon secure channel. Microsoft is blaming not only the KB5009555 update, but "updates released January 11, 2022" for the problem.
Microsoft re-releases KB5009624, KB5009557 and KB5009555 updates
The first Patch Tuesday of 2022 ended up being rather more dramatic that many would have expected -- and not for the right reasons. The company released the KB5009566 update which, along with another update, was later found to cause problems with VPN connections. But it was issue with Window Server updates that concerns system administrators.
No fewer than three updates were found to be problematic for different versions of Windows Server, ultimately leading to Microsoft halting the rollout of KB5009624, KB5009557 and KB5009555. And while the Hyper-V issues introduced by the patches are still to be fixed, Microsoft has nonetheless recommenced the rollout of the update, saying that it is investigating the problems.
Microsoft pulls problematic Windows updates that break Hyper-V and more
Problems with updates are hardly a new phenomenon for Microsoft, but 2022 has not got off to a good start. Not only were the KB5009543 and KB5009566 updates found to break VPN connections, another trio of updates has now been pulled because it contains critical bugs.
The KB5009624, KB5009557 and KB5009555 updates have been withdrawn because they are causing Hyper-V to stop working. The problematic updates have also be found to cause domain controller reboots and to render ReFS volume systems inaccessible.
