Microsoft has released optional out-of-band updates to fix a known issue triggering Kerberos sign-in failures and other authentication problems on enterprise Windows domain controllers after installing cumulative updates released during November's Patch Tuesday.
"After installing updates released on November 8, 2022 or later on Windows Servers with the Domain Controller role, you might have issues with Kerberos authentication," Microsoft explained.
Today, Microsoft has released OOB emergency updates that Windows admins have to install on all Domain Controllers in affected environments.
The OOB updates released today are available only via the Microsoft Update Catalog and will not be offered via Windows Update.
"If you are using security only updates for these versions of Windows Server, you only need to install these standalone updates for the month of November 2022," Microsoft added.
Two years ago, Redmond addressed similar Kerberos auth problems affecting Windows systems caused by security updates released with the November 2020 Patch Tuesday.
