Hi @Md. Rubiat Haque
To make an Active Directory server to be a slave server for a given zone, you must create slave records in that server's file. Separate records can designate the server as a slave server for the zone, the zone's reverse address domain, and the loopback host.
A slave record has three required fields:
-The first field designates the server as a slave.
-The second field identifies the zone it serves.
-The third field identifies the IP address of the master server for the zone from which the slave server obtains its authoritative data.
You get more information regarding this you can try contacting the Efficient IP to understand the process.
Hope this resolves your Query!!
