Your Internet access device can do NAT? I think that use DC to share internet is the worst option in this case. Better would be share using a workstation.

ON the DC make sure the Windows Firewall/Internet Connection Sharing service is enabled and running.
Set the LAN IP of the server as the default gateway for the PC's and you should be sharing the Internet connection from the server with the desktops at that point.
However, I don't consider this the best way to do it.
What you should do is install a business class firewall/router device such as Sonicwall, etc. Then manage Internet connectivity through there going directly to your ISP's modem.
The firewall/router can handle DHCP and NAT or you can still manage DHCP via the server which would be the preferred method.
If you are unfamiliar with doing this hire a competent IT firm to come in and do it for you. They should be able to get it accomplished in under 2 hours.

2. The default gateway would be that of your router - probably
3. Use as your DNS server (yes it points to itself)

Next, install the DNS services on your 2008 server.
Now, find out what the IP addresses of your ISP's DNS servers are.
In DNS Services, look for the option to create a forwarder. Use your ISP's DNS addresses as your forwarders.

Next, install the DHCP services on your server.
Setup a DHCP scope and include YOUR DNS server, and default gateway IP addresses.

Now your workstations should get their DHCP info from your server and be able to connect to the internet through the server.

To limit internet access, create a group policy. For those computers you don't want to access the internet, find the group policy for the connections tab for Internet Explorer. Add a proxy server and use the IP address of
