14 DAY TRIAL // Microsoft has confirmed another problem encountered by users after a recent Windows update, though this time, only Windows Server appears to be affected.
More specifically, Microsoft says that some apps and devices may no longer be able to create Netlogon secure channel connections after installing the January update that it published on Patch Tuesday.
The company explains that Windows clients aren’t affected, but on the other hand, devices running Windows Server 2008 SP2 and newer are prone to this problem.
“After installing KB5009555 or any updates released January 11, 2022 and later on your domain controllers, scenarios which rely on Read-only domain controllers (RODCs) or synthetic RODC machine accounts might fail to establish a Netlogon secure channel. RODC accounts must have a linked and compliant KRBTGT account to successfully establish a secure channel. Affected applications or network appliances, such as Riverbed SteelHead WAN Optimizers, might have issues joining domains or limitations after joining a domain,” the company explains.
Fix currently in the works
The work on a full fix is currently under way, but obviously, there’s no ETA as to when it could be released to users.
Microsoft says its investigation continues as we speak, as an update from the developer or manufacturer would be required to deal with the whole thing.
“Affected apps and network appliances will need an update from their developer or manufacturer to resolve this issue. Microsoft and Riverbed are presently investigating and will provide an update when more information is available,” it explains.
Needless to say, the only workaround should be the complete removal of the said patch, though on the other hand, it’s important to know that by removing the update, you also lose all the security improvements that it deployed on your computer. In other words, you shouldn’t do this because your Windows Server machine could end up exposed to outside threats.
