Hi everyone

I am getting these Kerberos Errors in my System Event Log at very regular intervals:

event id 594
A Kerberos Error Message was received: on logon session InitializeSecurityContext
Client Time:
Server Time:
Error Code: 0:34:44.0000 8/6/2003 (null) 0x7
Extended Error: KDC_ERR_S_PRINCIPAL_UNKNOWN
Client Realm:
Client Name:
Server Realm: <domain name>
Server Name: krbtgt/<domain name>
Target Name: DNS/prisoner.iana.org@<domain name>
Error Text:
File:
Line:
Error Data is in record data.


I have searched on the KB but couldnt find anything on this.... some clients on the network have reported slow login performance... just wondered if anyone can point out anything to this event log?

Regards

Richard
