When you deploy Active Directory in your environment, you must have a DNS infrastructure available to support the directory service. If you already have an existing DNS infrastructure, you need to integrate the Active Directory namespace into that environment. If you do not have a DNS infrastructure in place, you need to design and deploy a new DNS infrastructure to support Active Directory.

For the purpose of this design process, an organization does not have an existing DNS infrastructure if the following are true:

  • The organization does not have any existing DNS servers in the network infrastructure.

  • The organization does not have any clients that access DNS servers. This means that the organization does not rely on an external source, such as a network service provider, for DNS services.
