Installing DNS Server using Active Directory

The Active Directory Installation Wizard offers the option to install the DNS Server Service when you install Active Directory. When you create a new domain, after you have entered all the information necessary, the computer will attempt to locate a DNS server. If it fails to find one, the wizard will offer to install the DNS Server Service. You can choose to let the wizard do so, or you can choose No, I will install and configure DNS myself. Active Directory is dependent on DNS and will not work without a DNS server.
Installing a Domain Name System (DNS) server involves adding the DNS server role to an existing Windows Server 2008 server. You can also install the DNS server role when you install the Active Directory Domain Services (AD DS) role.
This is the preferred method for installing the DNS Server role if you want to integrate your DNS domain namespace with the AD DS domain namespace.

Steps To install DNS server

  1. Open Server Manager. To open Server Manager, click Start, and then click Server Manager.
  2. In the results pane, under Roles Summary, click Add roles.
  3. In the Add Roles Wizard, if the Before You Begin page appears, click Next.
  4. In the Roles list, click DNS Server, and then click Next.
  5. Read the information on the DNS Server page, and then click Next.
  6. On the Confirm Installation Options page, verify that the DNS Server role will be installed, and then click Install.

If you have existing DNS servers on your network, you need to be certain that your DNS implementation supports the necessary features for Active Directory to function. At a minimum, this entails support for SRV records that AD uses to locate domain controllers, Global Catalog servers, and site information. Your DNS servers should preferably support the following advanced features as well:
  1. Incremental Zone Transfers (IXFR)
  2. Fast Zone Transfers
  3. Dynamic Updates

Windows 2000/2003 DNS servers support these advanced features, as do UNIX BIND servers running version 8.2.2 or later. If your existing DNS servers do not support these features, install DNS on the domain controller itself and delegate control of the Active Directory DNS zone from your legacy DNS servers.
