DNS Set-up

I currently have a XServe running 10.3.4 Server that is sitting behind a router that is doing NAT and DHCP for the client machines on the network. We are going to use the server for the following: Mail Server Web Server Open Directory WorkGroup Manager DNS Ofcourse my question is about DNS. I am not sure how to configure the server so that DNS is properly working for each service above. Here is what I hav so far: Zones school.org master ns.school.org SOA Records in zone school.org localhost.school.org. IN A 127.0.0.1 router.school.org. IN A 10.0.1.1 (reverse) mail.school.org. IN A 10.0.1.2 (reverse) ns.school.org. IN A 10.0.1.2 (reverse) school.org MX mail.school.org. (5) What am I missing? I tried working with this before and when I added the DNS Server to the 10.3.4 client, WorkGroup Manger logged in very fast but the school website (default in Safari) would not launch. If I removed the DNS from the client the webpage would load but the log-in time increased to over 2 minutes. Will there be a conflict if the school.org is hosting our website and supplying DNS to the client? I know these are newbie questions but I am trying to learn. Thanks.
