instructions on creating secondary DNS

BrianMultiLanguage

Is this referring to the primary or the secondary?

"The next thing that you will have to do is to open the DNS console by
selecting the DNS option from the server’s Administrative Tools menu.
Navigate through the console tree to DNS | your server | Forward Lookup Zone
(be sure to click the plus sign next to the Forward Lookup Zone container
even though there are no sub-containers). Now, right click on the Forward
Lookup Zone container and select the New Zone command from the resulting
shortcut menu. This will cause Windows to launch the New Zone wizard."

We have the primary DNS server but no secondary.

Thank you.
