You must have a working Dynamic Name Services (DNS) server on the network to run Windows Deployment Services. Administrators may choose to dedicate an entire server to one role or to install multiple server roles on a single computer. For simplicity, the Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) roles can be installed together on one server.
Domain Name System (DNS) is the name resolution protocol for TCP/IP networks, such as the Internet. A DNS server hosts the information that enables client computers to resolve memorable, alphanumeric DNS names to the IP addresses that computers use to communicate with each other. Here is a summary:

Under Roles Summary, click Add Roles.
On Before You Begin, click Next.
