Recursive queries that named does for a client are different than your 
machine as a dns client reaching out to Google's recursive service.

You need to have UDP & TCP port 53 open to your recursive server(the one 
running named) first of all.  And if any network element within your 
network limits the size of UDP packets, you will have problems with 
EDNS0 queries.

On this box running named, try this:

dig +trace

dig +trace

After dig gets a copy of the root servers from the local named, it will 
do the same type of queries that a recursive name server does.
