Actually, as I think about it more, this won't work at all.  You would only
be retreiving the addresses and nameservers associated with the main domain
itself.  Nothing about subdomains would be listed in those types of records.
DNS is not designed to work that way.

Researching into this more, it turns out that you would need to perform a
"zone transfer" query instead, which unfortunately you may or may not be
able to perform as it usually requires special permission on the DNS server
you are connecting to.  It is primarily meant for DNS servers to exchange
database information with each other.  The 'nslookup' command-line utility
that ships with Windows NT4+ will allow you to retreive zone records for a
domain, provided you have it connect to a DNS server that allows zone
transfers.  You can use that for testing.  Have a look at the following
