Re: [Samba] Samba firts DC fail over




Just a thought if the client machines are still getting a listing in the
DNS for the failed machines wouldn't this be a problem? How would the
programs know not to use the failed server? Is there a way to temporarily
move the failed machines out of dns listings?
