Our plan for the Movie U. network is to run name servers on two hosts: terminator and wormhole. But a fresh installation of Windows Server 2003 doesn’t include the DNS server by default, so we need to install it on these hosts.
Start by selecting Start → Manage Your Server. This brings up the administrator’s one-stop-shopping application, Manage Your Server, as shown in Figure 4-2.
Choose Add or remove a role. The next window is titled Preliminary Steps and we don’t show it, but it just admonishes you to have the computer connected to the network and any peripherals and to have your installation media handy. After clicking Next on this screen, you might (or might not) see the Configuration Options screen, which gives you the option to install several common services all at once or pick and choose a custom configuration. We don’t show this screen either, but choose Custom configuration and click Next.
Now you’re presented with the Server Role window, shown in Figure 4-3. Select DNS server as shown in the figure and click Next.
The resulting window, Summary of Selections, describes the actions about to be taken. Click Next to install the DNS server and do some preliminary configuration. After the installation from the media completes, the Configure Your Server Wizard starts the Configure a DNS Server Wizard, which is shown in Figure 4-4.
If you want to, at this point you can review the checklists, but since we’re walking you through this process, select Next and you’ll see the Select Configuration Action window shown in Figure 4-5.
The wizard can helpfully create both forward- and reverse-mapping zones for you, but we’re going to show you how to do that outside the wizard. That’s why we suggest you select the third option, Configure root hints only. Don’t be scared off by the warning that this step is for advanced users only. Here’s what’s happening: after the wizard completes, your newly installed name server will not be authoritative for any zones and it will know only about the Internet’s root name servers. So it will know how to contact other name servers (starting with the root name servers) to resolve domain names, but it won’t know anything in particular about your organization’s zones—yet. Click Next and the wizard shows one more window telling you that it’s done. After clicking Finish on that window, you’re back to the Configure Your Server Wizard’s last window. Click Finish and, congratulations—you’ve installed the DNS server.
 We cover one method for installation here, but you could also install the DNS server using Active Directory, as described later in this section.
 The Configuration Options screen is apparently displayed only when you add the first role. After that, Windows assumes you know what you’re doing and doesn’t offer this shortcut to install multiple roles at once.
