Pre-Authentication Failure Event ID 675

    I am getting daily kerberos ticket events in the security log of my SBS2003
    server from a vista client.

    Security Event ID 675
    Pre-Authentication Failed
    Service Name: krbtgt/******
    Pre-Authentication Type: 0x0
    Failure Code: 0x19

    I have amended the UserAccountControl flag on the relevant computer account
    in AD but the event still occurs first thing each day (rather than at several
    times during the day).

    Can anyone help?
