The following post will comprise the steps on how to install a primary domain controller for a new forest.

Here we go!

First of all you will have to plan out your IP Addressing schemes, domain names, computer names, DNS infrastructure, DHCP scopes, Forest name, number of domain controllers, user account naming conventions, site links, group policies, etc. Once you have the above planned out according to your requirement you can go ahead with your Windows Server 2008R2 installation on the first server in your forest. the installation of Windows server 2008R2 is very simple and straight forward. When the installation is done and you log on to your server you will be given the Initial Configuration Tasks (ICT) window automatically for certain configurations of your server.

You can initiate the installation of the Active Directory Domain Services (AD DS) role from the ICT window or you can start the Server Manager and start the installation of the AD DS role. 

CaptureFrom the server manager click on Add Roles

add roles 2

On the Add Roles Before you begin instruction window click next (after you read)

select server roles 3

Select the Active Directory Directory Services Role

You will be prompted to install the .NET framework 3.5.1 features – click on add required features and click on next

Installation of the role finishes. If you see the above screen capture, it gives me a hyper link which says “close this wizard and launch DCPROMO.EXE” click on it and you will be prompted with the following screens (the DCPROMO welcome screen)


Click on next


On the Operating System Compatibility Screen – click next


On the deployment configuration page select – create a new domain in a new forest option (initial requirement)


Provide the Fully Qualified Domain Name (FQDN) of the forest root domain – here its TEST.COM – Click next


On the Forest Functional Level – Select The Appropriate level


Since there is no DNS server installed you will be prompted to install DNS server here


On the above message, Click “Yes and Continue”


On the Location for Database, Log files and SYSVOL window either you can browse and change or leave the default – click next


On the directory services restore mode password – Assign a password and you may need this password when you start your you domain controller in Directory Services Restore mode


Review the Summary page and click Next


The installation starts


After the Installation click on finish and the server reboots.

And that’s about it on how to install Active Directory on a Windows Server 2008R2.
