Hi,

You can always use an access control list or inbound filters configured
through Routing and Remote Access in win2003.

From a 3rd party scan -

desc:    This DNS server has query recursion enabled, allowing it to answer requests for DNS zones outside of your 
authority. This configuration may allow attackers to perform a cache poisoning attack on your server, corrupting then 
name-to-IP translation tables, potentially enabling man-in-the-middle attacks.
remed:  Check your DNS server documentation for instructions on either disabling recursion or limiting the hosts which may ask 
for recusrive queries. For example, in BIND 8, the 'allow-recursion' directive can be used for this purpose.


From what I have read, windows server 2003 DNS does have the ability to restrict recrsive lookups to a specific IP range, 
(my local network). It's either on or off, and off is not an option. Given that, what are the recommendations for a 
non-authoritative forwarder, Bind, tinynds etc?
