I have no problem pinging the ip addr. of the root servers.  When I start
named server in the debug mode, I can see that it's trying to contact 
the root servers but could not make connection.  As far as the firewall
is concern, I did open port 53 for both TCP and UDP.  Also, the cache
file is the one that we are using on our current DNS server and is up
to date.
Thanks for taking the time to response.  I will take your advise and look
into the firewall to see if it might be the problem.
