Windows Server 2025 | Kerberos Local Key Distribution Center (LocalKDC) service fails to start

Question

Hello,

After installing the latest cumulative update for December, KB5048667, on my Windows Server 2025 system, the Kerberos Local Key Distribution Center (LocalKDC) service fails to start due to the following generic exception:

• "Some services stop automatically if they are not in use by other services or programs."

This issue appears to be related to the recent changes regarding NTLM deprecation and the optional shift to Kerberos for local user authentication.

After uninstalling the cumulative update for December, the service gets stuck at START_PENDING and never starts, that gives me some chills.

Cannot find any events regarding the Local KDC service, even after enabling logging for Microsoft-Windows-Kerberos-Local-Key-Distribution-Center/Operational.

Given the importance of these changes, I’d like to report this as a potential issue with the latest GA implementation.

Is this a known issue with KB5048667?
