DNS on Windows Server 2003, 3rd Edition

Add an NS Record for the New Secondary Name Server

Your new secondary won’t be much good if the rest of the world doesn’t know about it. As a general rule, when you add another name server for a zone, you also need to add an NS record for it. (We’ll discuss the exceptions to this in Chapter 9.)

You need to add an NS record for the secondary on the zone’s primary. (Remember that all changes to a zone are made on the primary and propagate automatically to the secondaries. Don’t get confused by the fact that the DNS console lets you see all your name servers—you make the changes only to the zone’s primary.) In our case, we need to add an NS record for wormhole to the movie.edu zone. So we click on movie.edu under terminator and select Action → Properties. Click on the Name Servers tab and you’ll see a window like the one in Figure 4-31.

Figure 4-31. NS records for the movie.edu zone

This window shows that right now there’s only one NS record for the movie.edu zone, which specifies terminator.movie.edu as an authoritative name server. To add another, click Add and you’ll see the window shown in Figure 4-32.

Enter the name and IP address of the secondary name server and click OK.
