You need to dcpromo to demote them.  There is no PDC and BDC in W2K.

Thanks Glen, so what you are saying is when demoting a primary DC, it automaticaly tranfers control services to a secondary server on the domain? could you also explain to me the notion of inhouse dns server pointing to ISP dns. how does this work? Thanks!

Gleb (err.. my actual name :) no offence)

Unless it's the last dc, yes.  It then becomes a stand alone server.  
DNS should be set up as follows.  DNS server has itself and ISP dns server in it's dns settings.  Local machines should only have internal dns machine listed.  The reasoning is that if you want to go to http://wwww.dogsandcats.com, if your dns server has never resolved that site, it won't be in cache.  The server will then go to your isp, and once it's resolved, it will stay in local cache.  This means the next time you go to that site, your machine will only have to go the back room for name resolution, and you'll get to the web site faster.  OK?

Thanks Glen, that makes sense. Now I have to work out how to set it all up. I have removed the old DNS server, active directory has also copied successfully.
The old server was hosting our website which has been moved across to the new sever; our domain name has an IP address of 195.74.121.34 so all requests for, say americaneuropean.com are forwarded to that address by our ISP. Can you explain to me Glen how does our server know that it need to pick up requests for this IP, and how does it associate 195.74.121.74 with 192.168.0.1:80 where the website actually sits. I have used my intuition and created a Host record in americaneuropean.com Zone with the IP address 195.74.121.74 but nothing seems to be happening. Also I had a look at the Event Viewer and there were zillions of entries such as this

'Registration of the DNS record '_kerberos._tcp.dc._msdcs.americaneuropean.com. 600 IN SRV 0 100 88 gri.americaneuropean.com.' failed with the following error:
DNS server not authoritative for zone. '

Any ideas Glen?

PS. You know you are the greatest <lol>
