| Hi
If you allow your name servers to respond to recursive requests from the Internet, then you run the risk, To turn off recursion in Microsofts DNS Server use the regedit tool (or regedt32) to add the value NoRecursion to the Registry Key, HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters. Set the value type to REG_DWORD with a value of 1.

| If recursive query is allowed on your server the host can asks the DNS server to provide it with a definitive answer to its query, which means even if the DNS server doesn't know the answer it is the servers responsibility to go and find the correct answer.
If you disable this, DNS server will not resolve any queries other than those for which it is authorative, or in other words, those queries in its zone
