Question : Creating Server 2008 Domain

I have a simplistic setup, I have a DSL line which connects to a Linksys Cisco router, the router is then connected to a switch and users then connect directly. I DO NOT have a domain in place, instead we are still running a WORKGROUP environment.

I am testing a domain setup under these condition. I have created a Windows Server 2008 R2, which I want to use as a Domain Controller.

What would I need to consider here in terms of setting up DNS and DHCP,

The router has an internal IP address of 192.168.2.x, what would be the best way to configure my domain controller in these conditions, this is also really a test to see if it is workable.

Please let me know if I need to provide more information.

Answer : Creating Server 2008 Domain

Both DNS and DHCP should be installed and configured on your Windows 2008 domain controller.  Your server should be set with a static IP address in the 192.168.2.x subnet with the default gateway set to the router's IP address.  It should point to itself ONLY for DNS.

Your DHCP scope would be configured to start at using as the subnet mask for a basic class C network.  I use an exclusion list to handle IP addresses that will be statically assigned to your server, router, and any other devices that might require a static IP address. How many you exclude depends on how many machines will be on the network and how many static IPs you think you'll need.  You can also use DHCP reservations for this purpose, although for servers and routers you should definitely use static IPs.  Configure your DHCP scope options to use your router's IP address as the default gateway and your server's IP address as the ONLY DNS server.  This way, you'll be ensured that your workstations get the appropriate settings to be able to browse the Internet and your server.

Let me know if you need more specifics.
