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.
regards

Without any configuration, command outputs for troubleshooting you are not going to get very far on this. I suggest you run some troubleshooting commands on the client computer. resolv.conf isn't a good place to put DNS as it has no way of dealing with SRV records. It is better to make sure your DNS servers are working properly. Each DC should be a DNS server for the domain nslookup is a good start. I would start to see if it is sees what it is suppose to in DNS nslookup domainname or nslookup domainname <ip of active DC> you can use --type=SRV to get SRV records nslookup --type=SRV _ldap._tcp.domainname make sure all the needed resolves can be made from the clients. then try making the connections maybe use telnet (from the clients) to try and access the ports Maybe you have a firewall on your other servers that you need to turn off?
