[Sriram]

Hi all,

we have a Ethernet connection from an ISP which is just
the next building they have all the DNS servers,mail
servers etc..i wanna experiment in setting up DNS servers
with 2000 server know one thing :-

1. Is it possible to set up a DNS within our own
organisation and bypasssing that ISP's DNS servers ?

2. A mail server is there already with that ISP..can i
again set up my own mailserver within our zone ?

Thanks in advance

Yes, in fact, if you set up an AD domain (by running DCPROMO on the 2000
server) You must have a local DNS server. The DCPROMO process will ask you
if you want to configure DNS on the server.
In fact, before DCPROMO, I advise you to install DNS on the server *AND* use
the 2000 server's Private IP for DNS *only* configuring your your ISP's DNS
as a forwarder.

Yes, you can, however it is lot less of a headache if you set your local
mail server use your ISP's mail server as a "Smart Host". What I am
referring to is that your local mail server will recieve its mail from the
ISP's mail server and your mail server will send outgoing mail through the
ISP's mail server.
Using the ISP's mail server as a Smart host keeps you from having to set up
a reverse lookup on your mail server and an MX record for your mail server.
Your ISP can advise you better on how it would work. What it comes down to
is your ISP's mail server will store and forward mail for your domain and
give you some redundacy should you lose your connection temporarily.
