Installing a DNS Server when 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.
