Re: Empty Event 529



Kerberos logon failure events sometimes show up blank like this, when the
ticket can't be decrypted (and therefore the machine performing the logon
can't extract the information needed for the audit event.

Hi!

I'm getting numerous event 529s on a W2K3 SP1 server on our network.
However, all that is shown in the event is the following. So apart from
having an IP there's nothing else. Why are the other fields left blank?

Event Type: Failure Audit
