Kerberos

Anyone ever run across event id 537 on Win2k Pro? I’m seeing this error throughout my security log. In checking www.eventid.net , there are suggestions to enable Kerberos event logging in the registry. One of the other things mentioned in the log are the possibilities of a forged SID on the network.

Has anyone ever heard of this before? If so, are there any good overviews on Kerberos and how it works?

Thanks for any info.
