    Howdy-

    In some of our DCs, we see an inordinate amount of Event ID 675s in the Security Log; they
    appear to be originating primarily from Macintosh clients that are bound to AD. Is there
    anything that can be done (server-side or client-side) to eliminate these specific errors?

    Pre-authentication failed:
    User Name: machine$
    User ID: DOMAIN\machine$
    Service Name: krbtgt/DOMAIN.COM.EDU
    Pre-Authentication Type: 0x0
    Failure Code: 0x19
    Client Address: 10.10.10.55 (IP address)

    TIA,
    BM
