Windows 10 Authentication Errors Fixed Via Update
Microsoft has started distributing an unscheduled update for Windows to fix authentication errors related to Kerberos tickets. The problem is addressed in Windows 10 version 1607 and 1809 and is thus made available for the LTSC.
Microsoft has released an out-of-band cumulative update to address a known issue. This emergency update is currently offered for Windows 10 Enterprise 2019 LTSC, Windows 10 IoT Enterprise 2019 LTSC, Windows 10 IoT Core 2019 LTSC, and Windows Server 2019. This means that only users who pay for the updates as part of the Long Term Servicing Channel receive it. The bug fixes are also available for other, older Windows Server versions.
