You are a systems engineer for your company. Your company has 20，000 users in a large campus environment located in Los Angeles. Each department in the company is located in its own building. Each department has its own IT staff， which is responsible for all network administration within the building.  
The company’s network is divided into several IP subnets that are connected to one another by using dedicated routers. Each building on the company’s main campus contains at least one subnet， and possibly up to five subnets. Each building has at least one router. All routers use RIP version 2 （RIPv2） broadcasts.  
The company acquires a new business unit located in Denver. The Denver office has 25 users. The network in the Denver office is connected to the network at the main campus by using a leased frame relay connection. The network administrator at the Denver office installs a Windows Server 2003 computer and configures Routing and Remote Access on this server. The network administrator at the Denver office configures this server as a router and implements RIPv2 in Routing and Remote Access.  
Later， the Denver administrator reports that his router is not receiving routing table updates from the routers on the main campus network. He must manually add routing entries to the routing table to enable connectivity between the locations. You investigate and discover that the RIPv2 broadcasts are not being received at the Denver office. You also discover that no routing table announcements from the Denver office are being received on the main campus network.  You need to ensure that the network in the Denver office can communicate with the main campus network and can send and receive automatic routing table updates as network conditions change.

You are the systems engineer for Contoso， Ltd. The internal network consists of a Windows NT 4.0 domain. The company maintains a separate network that contains publicly accessible Web and mail servers. These Web and mail servers are members of a DNS domain named contoso.com. The contoso.com zone is hosted by a UNIX-based DNS server running BIND 4.8.1.  
Contoso， Ltd.， is planning to migrate to a Windows Server 2003 Active Directory domain-based network. The migration plan states that all client computers will be upgraded to Windows XP Professional and that all servers will be replaced with new computers running Windows Server 2003.  
The migration plan specifies the following requirements for DNS in the new environment：
•  Active Directory data must not be accessible from the Internet.
• The DNS namespace must be contiguous to minimize confusion for users and administrators.  
• Users must be able to connect to resources in the contoso.com domain.
• Users must be able to connect to resources located on the Internet.  
• The existing UNIX-based DNS server will continue to host the contoso.com domain. 
• The existing UNIX-based DNS server cannot be upgraded or replaced.
You plan to install a Windows Server 2003 DNS server on the internal network.
