kerberos errors

[guitar_madness]

I have enabled kerberos logging on the clients on my system and when
they successfully log in I get two errors in the system log. They are
identical expcept one appears to be for the sql server and the other is
for the file server.

These are the logs I get:

--------------------------------------------------------------------------------------------------------------

If you have not seen it yet the white paper in the link below may be of help
and references KDC_ERR_S_PRINCIPAL_UNKNOWN errors and the reason why.
Hopefully something in it will help. -- Steve
