In November 2022, Redmond released emergency out-of-band (OOB) updates to fix another known issue triggering Kerberos sign-in failures and various other authentication problems on enterprise Windows domain controllers. It also addressed authentication failures related to Kerberos delegation scenarios on Windows Server in November 2021 and similar Kerberos auth problems affecting domain-connected devices running Windows 2000 and later one year earlier. Microsoft has fixed a known issue causing authentication problems when Credential Guard is enabled on systems using the Kerberos PKINIT pre-auth security protocol. Because of this failure, devices are perceived as stale, disabled, or deleted, leading to user authentication issues," Microsoft explained in a Windows release health dashboard update. Microsoft says the issue was fixed in April 2025 with Windows security updates for Windows 11 24H2 and Windows Server 2025. However, because Kerberos Authentication is most commonly used on enterprise endpoints, home devices are likely not impacted by this known issue.
