You've posted to a mailing list which is focused on the BIND server, which
runs predominantly on Unix systems. So you're a bit off-topic for this

Yes. The client sends all DNS queries to the server.

Look at the server configuration some more. Somewhere in there it is
configured to forward DNS queries to Internet servers, maybe the same ones
that got automatically configured on your ADSL router.

Yes, the DNS server on the server receives a query fron the Win98 client,
forwards it to an Internet DNS server (probably ones operated by your ISP)
and sends the answer back to the client. If you ran a network packet
sniffer ( such as Ethereal ) on your server, you would be able to see this

For this small home/SOHO network, anything that works is probably the
ideal configuration. What you've got now sounds OK.
