I'm trying to list the actual primary zone setting for the secondary zones. The SOA record shows what one puts in as the master or primary zone. But the zone's actual primary is listed in the General tab of the properties window. I'd like to know if the dnscmd, or for that matter any other command, can retrieve that information instead of what the SOA record lists.

The reason that those can be different is if you are sending some zones to a secondary name server that sits on the internet. You want your customers to resolve the domain's records but you don't want to know that the primary is actually some server you have inside the firewall.
