Order Instructions:

You are the network administrator for Contoso, Ltd. The Contoso headquarters’ network consists of a single domain, contoso.com, which is protected from the Internet by a firewall. The firewall runs on a computer named NS1 that is directly connected to the Internet. NS1 also runs the DNS Server service, and its firewall allows DNS traffic to pass between the Internet and the DNS Server service on NS1 but not between the Internet and the internal network. The DNS Server service on NS1 is configured to use round robin. Behind the firewall, two computers are running Windows Server 2003 – NS2 and NS3, which host a primary and secondary DNS server, respectively, for the contoso.com zone. Users on the company network report that, although they use host names to connect to computers on the local private network, they cannot use host names to connect to Internet destinations, such as http://www.microsoft.com.
