Kerberos KDC Errors

Copper Contributor

Hello,

I have been testing Windows Server 2025 with AD DC role and sometimes in event log I can see error.

The Security Account Manager failed a KDC request in an unexpected way. The error is in the data field. The account name was and lookup type 0x108.

Just a note - I did not remove the account name; it is not just there, not even once.

I'm unable to connect it to some "action", so it looks a bit random. In data field there is only C000000D (in words) which is every time the same. Event ID is 7.

Is this okay or anything to worry about?
