W2K DNS Zone Update

My ISP is complaining that they're getting requests from my network to
update DNS. Since they are authoritative for our domain, they rejects
these zone updates. I used WireShark to find the problem machine,
which is running Windows 2000 server. "Dynamic update SOA
xxxxxxxxx.com" The DNS packet details show that this machine is
trying to install an A record and a CNAME record with this machine's
name into the authoritative DNS.

I looked at services and see that this machine is running DNS client
(but not server). Why is it trying to update the authoritative DNS?
How do you manage the DNS client on W2K Server? Is it possible to
turn off this behavior?

How do you setup the DNS? It is better to use internal DNS.
