Yes as long as it's authorized to serve DNS it will do so, make sure you have no roles on that server before dcpromo is run.

All the Active Directory Integrated zones will be gone once you demote it so no it won't work for any of those zones which means issues for your clients.
Just install DNS on the 2008 boxes if you haven't already and point the clients (DHCP and static) to the 2008 boxes for DNS.

authorized is associated with DHCP servers not DNS.

ok let me clarify whats going on here.
all dc's seem to be running active directory integrated dns fine.
all my worstations are pointing to their main dns server as the one im about to demote.
i already changed in dhcp for new leases to get the updated settings but that will take a week or so to point clients to the new proper dns server.

if i demote this 2003 dc that is running active directory dns for my domain. im guessing that all the clients that have it as its numero uno dns server will loose dns services.
i guess ill just wait till new dhcp setttings take affect.

Yes wait for DHCP to update with the new info,
So next time you do something like this a week or so before (depending on your DHCP lease times) lower the lease to 4 hours (something short).  Then you make the change (in your case demotion) after hours and by the next day they should be updated.
Then you can set your lease times back to your default/longer period when you are done.
Thanks
