    I have seen many port regarding a Event ID 675 Pre-Authentication Error
    for kerberos but I haven't found any answers.

    Eventid 675
    service name : krbtgt/<domain>
    Pre-Authentication Type 0x0
    Failure code :0x19
    Client Address: is the win2k8 server

    The account in question is a AD account used to authenticate a app to a
    SQL server.

    The App is on a win2k8 x64 server and the SQL server is a Win2k3 R2 x64
    server. The Domain is a Win2k3 native, runing on 3 DC all Win2k3 R2 X64.

    Is there a known issues with Server 2008 with these errors ?

    any help would be greatly appreciated.
