If you already have servers running locally for your site, why did they
delegate your subdomain to those other nameservers?

I'm having trouble understanding the problem you're trying to solve.  You
start out saying that you can't look up *external* named, by which I assume
you mean things like www.yahoo.com.  But then you said "I'm now attempting
to connect our sub domain to our parent domain".  Which names are you
having trouble looking up -- names in company.com or names outside of
company.com?

To look up external names, you just need to be able to communicate with the
Internet.  The db.cache file tells you where the root servers are, and
they'll tell you where the servers for yahoo.com are, and your server will
query them.  If this doesn't work, a common reason is that your company has
a firewall that's blocking the queries or the responses -- they need to
allow port 53 back in to your nameservers.  If they only want to allow DNS
in to the main corporate nameservers, you could configure your local
nameservers to use them as "forwarders".
