Domain Name System free essay sample

Your first task is to design that namespace by specifying appropriate domain and host names for the computers in the division. | Completion time| 15 minutes| 1. Design a DNS namespace for your organization that conforms to the following guidelines. a. The root domain name for the test DNS namespace is Contoso##. com, where ## is the number assigned to your computer by your instructor. All of the additional domains that you create must be subordinate to this domain. b. The internal network must be located in a different domain from the external network. The organization consists of three internal divisions: Sales, Human Resources, and Production. Each division must be represented by a separate subdomain in the namespace. d. Each division has departmental servers performing various roles and as many as 200 workstations, only some of which are shown in the diagram. Your host names should identify the function of each computer. e. Three servers on an external perimeter network host the company’s Internet services: In the diagram provided in Figure 2-1, write both the domain names and the fully qualified domain names that you have selected for the computers in the appropriate spaces. But since only some of the workstations have got addresses the problem might be the DHCP server. Start off by doing some ping tests to verify that the DHCP server is able to communicate across the network. If the DHCP server is able to communicate with other computers on the network, then I recommend verifying that the DHCP server has an IP address that is compatible with the scope that the server is configured to assign addresses from. The server itself has to be assigned a static address in the same subnet range, such as 192. 168. 0. 199. If this still doesn’t solve the problem make sure that the DHCP server is still authorized by the Active Directory to lease IP addresses. You should also check to verify that the scope is active, and that the necessary services are running on the DHCP server. Exercise 1: DNS scenario. You will need to setup a primary DNS server in the larger branch office. Configure it as a primary forward lookup zone for the domain name of your company. Before you install DNS make sure your computer has a static ip address so it does not get one from the DHCP server. In the small branch setup a second DNS server. Configure it as a secondary forward lookup zone with the same domain name as the primary DNS server.
