Gaurav,
You have two options. Either you should set up a roots.hints file
which will tell your DNS server where the root name servers are located,
or you can rely on the fact that your ISP will have done this. The second
approach invovles you appending your ISP's domain name on the 'search'
line of resolve.conf, and also specifying (in addition to yours) their
nameservers.
The first approach is more involved. I would suggest reading the
DNS-HOWTO in order to do that. Or the 'DNS and BIND' book by Albitz and
Liu.
Regards,
Kenneth
