AD in Windows 2008 R2


This article provides prerequisites and steps for installing Active Directory Domain Services (AD DS) on Microsoft Windows Server 2008 R2 Enterprise 64-bit (W2K8). This article does not provide instructions for adding a Domain Controller (DC) to an already existing Active Directory Forest Infrastructure.

Prepare for Active Directory


Before you install AD DS on a Rackspace Cloud Server running Windows Server 2008 R2 Enterprise 64-bit (W2K8), you must perform the following prerequisite tasks.

Select Domain Name and Password


Select your domain name and know the domain administrator password that you want to use.

Note: Although it is not required, we recommend that you use a multiple name format for your domain name. For example, use domainName.com or domainName.local rather than simply domainName.

Specify the Preferred DNS Server


Windows Server 2008 can properly install and configure DNS during the AD DS installation if it knows that the DNS is local. You can accomplish this by having the private network adapter’s preferred DNS server address point to the already assigned IP address of the same private network adapter, as follows:

Note: The last step for prepping W2K8 for AD is adding the proper Server Role. The “Active Directory Domain Services” Role will be added. This only installs the framework for W2K8 to become a DC and run AD. It does not promote the server to DC or install AD.

Add the Active Directory Domain Services Role


Adding the Active Directory Domain Services role installs the framework for Windows Server 2008 to become a DC and run AD DS. It does not promote the server to a DC or install AD DS.

Enable the Remote Registry


Install Active Directory Domain Services (DCPROMO)


Now that you have prepared the server, you can install AD DS.

Tip: As an alternative to performing steps 1 through 3, you can type dcpromo.exe at the command prompt. Then, skip to step 4.


The installation examines and verifies your DNS setting.

The installation of Active Directory Domain Services on your server is complete.
