Lab 3: Domain Name Services/3
Now that the DNS service is installed, it is time to configure it. When the service is run for the first time, it asks to configure the root name server. If you are connected to the Internet, DO NOT configure a root name server (you would only do this if you were creating an Intranet and your company had no Internet connection).
19. Click Start, Programs, Administrative Tools, DNS
20. The DNS management tool is now displayed. Your computer should appear as an icon in the left pane window.
 |
Click on the computer icon to display the message as shown in this example. |
A DNS server uses zone files (forward and reverse) to perform lookup requests. In each zone file records are used to map computer names to IP addresses. In the following section you will create a forward and reverse zone for your network, and create records that map computer names to IP addresses.
21. Click Action then Configure the server. The Welcome to the Configure DNS Wizard appears. Click Next.
 |
Specify the option "This is the
first DNS server on the network". Click NEXT. |
22. It is now time to create a forward lookup zone that will resolve computer names to IP addresses.
 |
Select the option "Yes, create a
forward lookup zone". Click Next. |
23. Select "Standard Primary". Click NEXT.
24. The New Zone Wizard dialog box requests the name for the zone. Enter the name that has been assigned to your domain as given to you by your instructor (this example uses domain.com).
 |
Once you have entered the correct name for the zone file, click NEXT. |
25. The dialog box now displays the name that will be used to the new zone file.
 |
Leave the filename as suggested, then click NEXT. |
26. Select the option "Yes, create a reverse lookup zone". Click NEXT.
27. Select the zone type as "Standard primary". Click NEXT.
28. A reverse zone maps IP addresses to computer names, so it has to know what range of IP addresses it will be responsible for.
 |
Enter the first 3 octets of the IP
address that has been allocated to your network domain by
the instructor. After entering the network ID, click NEXT. |
29. The wizard will display the name of the reverse zone file that it will create.
30. What is the name of the reverse file?
____________________________________________________
31. Click NEXT.
32. Click FINISH so the wizard will create the reverse lookup zone.
 |
Click FINISH to create the primary zone
and the zone file.
|
You have now successfully created a primary zone (domain.com) and forward zone lookup file.
Double-click on the computer icon to expand the tree and display the forward lookup zone.
