You are the network administrator for Company.com. The network consists of a single Active Directory forest that contains one domain named Company.com. You need to deploy a new domain named NA.Company.com as a child domain of Company.com. You install a new stand-alone Windows Server 2003 computer named ES1. You plan to make ES1 the first domain controller in the NA.Company.com domain.

You configure ES1 with a static IP configuration. You run the Active Directory Installation Wizard on ES1. The wizard prompts you for the network credentials to use to join the NA.Company.com domain to Company.com.

You receive an error message stating that a domain controller in the Company.com domain cannot be located. You need to be able to promote ES1 to a domain controller as the first domain controller of the child domain in the existing forest.

What should you do?

A.
Configure the client WINS settings on ES1 to use a WINS server that contains entries for the Company.com domain controllers

B.
Configure the client DNS settings on ES1 to use a DNS server that is authoritative for the Company.com domain

C.
Configure the DNS Server service on ES1 to have a zone for NA.Company.com.

D.
Configure ES1 to be a member server in the Company.com domain.
