Here is a basic review of my network I want to build. 4 PC's 1 Xbox. Now for the hardware. I have one pc with two nics in it with Server 2k3 installed on it. I am also using a switch which complicates things a tad. My ISP is Comcast. What I want to do is run the line from my "modem" into the first nic on my server and then run a line out into the switch which is where my other three computers and Xbox are hooked up. Im not really sure how to go about doing this. I know I need to set up my server as DHCP/DNS but after that Im pretty lost. Im sure there is alot of information I didnt put up so please let me know if you need more info. Thanks.
