Complicated Domain Controller Question

ctm2k · 05-31-2006, 07:46 PM

Hey everyone I have a complicated questions involving a home network im attempting to setup.

I have my desktop running windows 2003 server running
Active Directy
DHCP
DNS
Domain Controller
With 2 NIC cards
One connected to MY DSL Internet modem
One running a crossover cable to the laptop
I have my laptop running xp pro

I created a domain on my desktop called simply Meridian. Now I can connect to the domain through the laptop. But once im logged in my dhcp doesnt assign any addresses etc. Now what im trying to have my laptop connect to the domain and be able to access the internet through the server? Is this possible with the setup I am attempting to run? How would I go about accomplishing this?

Thanks

You want to enable internet connection sharing.

However, instead I recomend buying a router and use it for the internet connection. You may want to run DHCP off yoru server still as domain members will be added into DNS

How do I enable ICS I cant seem to find it. And will i need to assign any ips to the 2nd network card on the server and to the NIC on the laptop?

This is ICS

As a general rule I recomend AGAINST using this. One of the warnings on this page also advises against it. Seriously get hardware routers.

On the 2003 server make sure the 2nd NIC is assigned an IP address statically in your DHCP scope that you setup.

For example your DHCP scope is 192.168.1.1 /24 to 192.168.1.254 /24, you'll need to exclude out atleast 1 address from that range for the NIC. I would exclude out 192.168.1.1, then assign that address manually to the 2nd NIC with the correct subnet mask. There is no need for a default gateway or DNS on that interface.

You also want to configure the DHCP scope option to give out address to the default gateway(003) and the DNS server (006) to the clients.

Make sure DHCP is activated, then simply plug the laptop onto that NIC with a cross-over cable and set it's NIC to automatically obtain an IP address and DNS. Doing ipconfig /release and ipconfig /renew in command prompt will help you obtain an address.

Afterward you'll need to verify that you can ping the interfaces that you are connected to before you setup RRAS and turn the 2003 server into a NAT router to share the Internet.
