Creating Zones from the Command Line If you have a lot of zones to create, you
can wear out your clicking finger by using DNS Manager. For those who enjoy using the
command line, Dnscmd.exe has DNS creation and configuration options. To see the syntax for
Dnscmd.exe and get help information, type dnscmd /? at a command prompt. The basic syntax
is dnscmd server / command plus command parameters, if required. Following are some exam-
