In
this article, we will configure an Additional Domain Controller sometimes also
known as ADC. An ADC is usually configured for redundancy. In a situation wherein
your Main Domain Controller fails, the ADC can service authentication requests
and it also helps in load balancing access to Active Directory.
As
always, ensure that your Server has a proper name and a valid IP address. Join
the Server to the domain, but this is not a strict requirement.
Ensure
that the Active Directory Domain Services role is installed, for instructions
on the same click here
After the Active Directory
Domain Services Roles is installed, click on Promote this server to a domain
controller
On the Deployment
Configuration page select “Add a domain controller to an existing domain” and
click on next.
On the domain controller
options page, make sure that only DNS Server and Global Catalog Server is
selected, type in the DSRM password, this can be any password that you choose
and click next. (make sure that the password has alphabets, special characters
and numbers )
On the
DNS delegation page, click next
Do not select the option
“Install from media” and click next. To learn about “install from media” click

Select the location of the
Database, logs and SYSVOL folder. The usual recommendation is to store
the Database and logs on separate drives for performance and recoverability
purposes. In case you want to know the details of the Active Directory folders

On the review options page, click
next
Allow
the computer to restart
