Installing and Configuring Active Directory
by Chris Sobeck
NOTE: Requires Windows 2008 Server to be setup as a Secure DNS server.
- Open Server Manager. Click Start, point to Administrative Tools, and then click Server Manager.
- In Roles Summary, click Add Roles.
- If necessary, review the information on the Before You Begin page and then click Next.
- On the Select Server Roles page, click the Active Directory Domain Services check box, and then click Next.
On a server that runs Windows Server 2008 R2, you might have to click Add Required Features to install .NET Framework 3.5.1 features before you can click Next.
- If necessary, review the information on the Active Directory Domain Services page, and then click Next.
- On the Confirm Installation Selections page, click Install.
- On the Installation Results page, click Close this wizard and launch the Active Directory Domain Services Installation Wizard (dcpromo.exe).
- On the Welcome to the Active Directory Domain Services Installation Wizard page, click Next.
You can select the Use advanced mode installation check box to get additional installation options.
- On the Operating System Compatibility page, review the warning about the default security settings for Windows Server 2008 and Windows Server 2008 R2 domain controllers, and then click Next.
- On the Choose a Deployment Configuration page, click Create a new domain in a new forest, and then click Next.
- On the Name the Forest Root Domain page, type the full Domain Name System (DNS) name for the forest root domain, and then click Next.
Although Dcpromo.exe in Windows Server 2008 and Windows Server 2003 allows you to create a single-label DNS domain name, you should not use a single-label DNS name for a domain for several reasons. In Windows Server 2008 R2, Dcpromo.exe does not allow you to create a single-label DNS name for a domain. For more information, see http://go.microsoft.com/fwlink/?LinkId=92467.
- If you selected Use advanced mode installation on the Welcome page, the Domain NetBIOS Name page appears. On this page, type the NetBIOS name of the domain if necessary or accept the default name, and then click Next.
- On the Set Forest Functional Level page, select the forest functional level that accommodates the domain controllers that you plan to install anywhere in the forest, and then click Next.
- On the Set Domain Functional Level page, select the domain functional level that accommodates the domain controllers that you plan to install anywhere in the domain, and then click Next.
The Set Domain Functional Level page does not appear if you select the Windows Server 2008 forest functional level on a server that runs Windows Server 2008 or if you select the Windows Server 2008 R2 forest functional level on a server that runs Windows Server 2008 R2.
- On the Additional Domain Controller Options page, DNS server is selected by default so that your forest DNS infrastructure can be created during AD DS installation. If you plan to use Active Directory–integrated DNS, click Next. If you have an existing DNS infrastructure and you do not want this domain controller to be a DNS server, clear the DNS server check box, and then click Next.
If you do not have static IPv4 and IPv6 addresses assigned to your network adapters, a warning message might appear advising you to set static addresses for both of these protocols before you can continue. If you have assigned a static IPv4 address to your network adapter and your organization does not use IPv6, you can ignore this message and click, Yes, the computer will use a dynamically assigned IP address (not recommended).
We recommend that you not disable the IPv6 protocol.
If the wizard cannot create a delegation for the DNS server, it displays a message to indicate that you can create the delegation manually. To continue, click Yes.
- On the Location for Database, Log Files, and SYSVOL page, type or browse to the volume and folder locations for the database file, the directory service log files, and the SYSVOL files, and then click Next.
Windows Server Backup backs up the directory service by volume. For backup and recovery efficiency, store these files on separate volumes that do not contain applications or other non-directory files.
- On the Directory Services Restore Mode Administrator Password page, type and confirm the restore mode password, and then click Next. This password must be used to start AD DS in Directory Service Restore Mode for tasks that must be performed offline.
- On the Summary page, review your selections. Click Back to change any selections, if necessary.
To save the selected settings to an answer file that you can use to automate subsequent AD DS operations, click Export settings. Type the name for your answer file, and then click Save.
When you are sure that your selections are accurate, click Next to install AD DS.
- You can either select the Reboot on completion check box to have the server restart automatically or you can restart the server to complete the AD DS installation when you are prompted to do so.
