how to configure additional domain controller in windows
server 2003 in network & in backup

Answer Posted / chandra

The Windows Server 2003 operating system supports
multi-master replication—all of a domain’s domain
controllers can receive changes made to objects and can
replicate those changes to all other domain controllers in
that domain. By default, the first domain controller created
in a forest is a global catalog server, which contains a
full replica of all objects in the directory for its domain
and a partial replica of all objects stored in the directory
of every other domain in the forest.

Replicating Active Directory data among domain controllers
provides benefits for information availability, fault
tolerance, load balancing, and performance. In this
step-by-step guide, you can take advantage of the greater
fault tolerance provided in the multi-master model by
installing multiple domain controllers. In the event a
domain controller stops working, the availability of Active
Directory is not compromised.

server 2003 follow this procedure

Note:-Before doing this procedure you need to make sure you
have domain controller setup in your win server 2003 with
DNS and you need to install DNS server and don’t configure

folders, or click Browse to choose a location, and then
