Okay... Here it is...

I'm doing work for my church and I have a T-1 Modem By Netopia....
And A firewall Sonicwall
And a D-LINK Router ... (Which I want to disable DHCP and use as a
Wireless AP Only)
I want to setup DHCP Through a Windows 2000 Server Box.. It has 2 NIC
Cards... How can I go about doing this setup? Also I have three servers
E-mail Exchange- DNS those all however have Public Static IP'S that I
cannot Change.... Can someone help? Thanks

If you're not in a windows domain, why not just use the router for DHCP
addresses? It's pretty much a "check the box" kind of thing. Most routers
let you limit the range of your DHCP scope so you can leave some for
statics.

If this is a Windows domain (as suggested by the fact that you are running
Exchange), I would suggest a good book or two on Windows server
administration. But in case I'm reading too far between the lines, the steps
to set up DHCP on a Windows server are:

1) Go to Add/Remove Programs
2) Go to Add Windows Components.
3) Under Networking, Select DHCP
4) After installation is done, go to Administrative tools.
5) Open the DHCP snap-in
6) Create and activate a scope
7) Configure scope and server options
8) Authorize the server.
9) verify that the DHCP service is started.

To add to Kurt's advice - "all those public static IPs" are not to worry
about. Those addresses will not be visible inside your network if it is
configured correctly. NAT should be turned on at the router to add a layer
of protection between your network and the rest of the world.

Cool...

Thanks... But Once I enable DHCP on that server that I'm making the
DHCP What is the configuration... Does the T1 Modem plug directly in
the firewall then to the Server?

What about the D Link? I 'm i hooking that up to the switch? The DHCP
Server has two NIC Cards.. Does that assist in anything?

I think - and take this with a grain of salt, as I am not familiar with your
firewall - you should hook up the T1 modem to the firewall, then the
firewall to the D-Link router, then all PCs to the router. That should
maximize protection and minimize exposure.

Unless you are putting the two network cards in the server on different
address ranges, disable one of them and leave it disconnected. You really,
REALLY don't want two network cards in the same address range in the same
server.

The only change I'd make to the above is if you are running a domain on your
network - if so, then disable DHCP on the router and turn it and DNS on
within the network. Otherwise let the router hand out addresses since this
is a much simpler set-up for a simple network.

What exactly do yo mean ?

When i make the server a DHCP Server.. doesnt it automatically assign
addresses to the LAN once its on the switch?

First, you don't want to hook up both network cards because you will wind up
with people being unable to locate the server and/or mysterious network
errors. Your server should only have one network card hooked up if you have
only one address range (which you do).

Second, you want only one DHCP server running on the network because if you
have two you will almost surely wind up with IP address conflicts. There's
a way to avoid that but it's unnecessarily complex for your setup. I
recommend using the router's DHCP because it's generally easier to
administer and troubleshoot. But it's your choice - whatever you decide,
server or router to be the DHCP server, there can be only one.
