multi-homed dhcp

Based on this diagram, how would you go about adding internet to all segments?

You'd need routers on all three subnets, which could all be the same machine. The DHCP server could also be a router (and dns forwarding possibly), either forwarding to another network or just directly attaching to the net.
Lets assume 4 ethernet adapters, eth0 eth1 eth2 and wan0, connected to subnets a, b, c and a cable modem respectively.
eth0 IP: 192.168.0.1 DHCP pool 192.168.0.2-254 assigns gateway 192.168.0.1/dns 192.168.0.1
eth1 IP: 192.168.1.1 DHCP pool 192.168.1.2-254 assigns gateway 192.168.1.1/dns 192.168.1.1
eth2 IP: 192.168.2.1 DHCP pool 192.168.2.2-254 assigns gateway 192.168.2.1/dns 192.168.2.1

(assume the cable modem works under the 192.168.100.0/24 subnet and routes at .1)
wan0: 192.168.100.2 gateway 192.168.100.1 dns assigned by dhcp

The routing table would be pretty simple on the server:
192.168.0.0/24 -> eth0
192.168.1.0/24 -> eth1
192.168.2.0/24 -> eth2
default -> wan0

How to actually configure Windows to do that I don't know, but thats the higher level description of how it works.

Xipher's right, you have not stated anything you are trying to do. The article explains you need to have a windows 2K3 server with 3 network cards. Next step would be how do you configure DHCP on 2K3 server? Try google or even the built in help. There is no do step A, B, C, D, etc because every setup is different. What equipment do you have? Do you really need to use 2K3 for DHCP? How many nodes are on each segment you are trying to setup? Do you really need different networks?

All that info will at least give us a place to start if you really need help.

If you're working in an environment where that is needed, more than likely you have vlan capable equipment, so you could do it with a single NIC machine.
