Hi,

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?
