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.
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 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.
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.
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.
On the Select Server Roles page, select the Active Directory Domain Services check box, and then click Next on this page and on the Confirmation page.
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.
On the Welcome page of the Active Directory Domain Services Installation Wizard, ensure that the Use advanced mode installation check box is cleared, and then click Next.
On the Operating System Capability page, click Next.
On the Choose a Deployment Configuration page, select Create a new domain in a new forest and then click Next.
On the Name the Forest Root Domain page, enter the domain name that you choose during preparation steps. Then, click Next.
After the installation verifies the NetBIOS name, on the Set Forest Functional Level page, select Windows Server 2008 R2 in the Forest function level list. Then, click Next.
The installation examines and verifies your DNS setting.
On the Additional Domain Controller Options page, ensure that the DNS server check box is selected, and then click Next.
In the message dialog box that appears, click Yes.
On the Location for Database, Log Files, and SYSVOL page, accept the default values and then click Next.
On the Directory Services Restore Mode Administrator Password page, enter the domain administrator password that you chose during the preparation steps. This is not your admin password that was emailed to you during the creation of your server, although you can use that password if you want to. Then, click Next.
On the Summary page, review your selections and then click Next.
The installation begins.
If you want the server to restart automatically after the installation is completed, select the Reboot on completion check box.
If you did not select the Reboot on completion check box, click Finish in the wizard. Then, restart the server.
After a few minutes, reconnect to your server by using the Console in your Control Panel or RDP.
To log in, perform the following steps:
a. Click Switch User, and then click Other User.
b. For the user, enter the full domain name that you chose, followed by a back slash and Administrator.
c. Enter the password that was emailed to you when you first built the server. If you changed your password
for the local admin account to this server before you began the installation of AD DS, use that password.
d. Click the log in button.
The installation of Active Directory Domain Services on your server is complete.
