The GUI setup of the DNS service, by default, allows anyone to do a zone
transfer from your DNS server.  To change this use the GUI.
Control Panel ==> services ==> DNS service parameters ==>add==>server
settings
In the Zone Transfer Access, enter the IP address of your secondary dns
server.  That way only that system could request a zone transfer.
