	If you are having a problem please state it as the original
	question got answered factually and did not indicate a error
	condition.

	The are many potential reasons why you could not be able to
	contact the root servers most of which are not BIND related at
	all.

	1. can you ping the root servers (use IP addresses)?

		Yes - good.
		No - routing problem / firewall problem / broken link.

	2. if 1 succeeds does "dig +norec ns . @<ip-address>" return the
	   list of root servers & their addresses for any / all root
	   servers.

		Yes - good.
		No - firewall problem (you may need to fix the source
		port / source address for queries in named.conf).

	Does the contents of root.cache contain have the NS and A records
	corresponding to the machines queried above?
