Service is krbtg/domainname.com
User Name is the Client Computer Name.

This shows me which client is experiencing the problem,
which is all of them. Kerberos requesting a renewal from
the Ticket Grant Service and fails. What this indicates to
me as this happens on start ups, password changes & just
about all the time. I know that computer passwords are
handled automatically, these are my Domain Kerberos
Settings for both Domain Controller & Domain policy.
Maximum lifetime for Service Ticket 600 minutes.
Maximum lifetime for user Ticket 10 hours
Maximum lifetime for user ticket renewal 10 days
Maximum tolerance for clock synch 60 minutes

Thanks Ondra,
Mike
