Setting up a Root name server

[Mark_Andrews at isc.org]

	Michael *both* you and chris are wrong as root servers do not
	"not respond" based on the setting of recursion desired.

	Whether you get an answer to the question asked or a referral
	is another question altogether and depends upon the question asked
	and what is currently being served.  But in either case you do
	get a response.
