Microsoft Windows Vista clients may be unable to join a PDC hosted on Mac OS?X?Server v10.5 or later. Windows Vista may be configured with a local security policy which does not include an authentication protocol that is required by Mac OS?X?Server v10.5 and later. Windows Vista clients may receive an alert similar to this when trying to bind to the Mac OS?X?Server PDC:? “Your computer could not be joined to the domain because the following error has occurred: Logon failure:?unknown user name or bad password.”
