Come on Brad - give the guy a clue *8-)

Two main situations where you don't ask the root name
servers questions....

1) You forward requests to your ISP's DNS servers.

Brad has argued elegantly why you don't want to do this -
that is why the list is archived, so you can go see if he is
right.

You need forwarder directives to do this.

2) Your network is deliberately disconnected from the
Internet (at least logically).

root.hints (or whatever it is called) is modified to point
to your own root name servers.

Modern versions of BIND have the Internet root nameservers
hardcoded, so if you delete the contents of root.hints,
you'll still talk to the root nameservers, you'll just use
more stale data to do it.
