Re: [Samba] Samba firts DC fail over




Hello.In my configuration I have three DCs one who build the domain and two replication. For the configuration of the client I put in the resolv.conf the three DC addresse. So normally the client is able to contact all DCs of domain. But to have domain information only the dc that built the domain provided them, and when I stop it, replication DCs are unable to provide this information to client machines.

 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?
