In a domain network, it is
important to have more than one DC so that if one DC fails, the other DC will
continue serving the clients. There is also load-balancing of Active Directory
Service if we have more than one DC.

Service if we have more than one DC.
The first DC we create is
simply called First DC and if we create an extra DC, then that DC is called
ADC. ADC has the same configuration of Active Directory as the First DC.

All the DCs in a domain network
are Masters. We can make any change in the Active Directory of any DC and that
change is replicated to all other DCs. Replication takes place among all the
DCs and it is controlled automatically. If we create a user in the First DC, it
is automatically created in the ADC because of replication.

All the DCs in the domain
network are peers and this model is called Multi-Master Model.

PRACTICAL
1.
Go to a 2003 server computer and configure it as DC with domain name as abc.com.
This will be your First DC.

2.To
create ADC, go to another 2003 server computer, in the TCP/IP properties, give
DNS address for xyz.com .If DNS is present in the First DC, just type the ip of
First DC in the ‘Preferred DNS server’ box.
