This is a step by step setup of how you get Windows XP to use Internet Connection sharing when you have a Cable Modem connection with the computer connected to the cable modem via NIC (1) and NIC (2) going to a hub (or a crossover cable to the other computer) and then having the secondary computer plugged into the hub also.
1. First off, left click on the "Start Button" on your taskbar. You will then right click "My Network Places" and select "Properties":
Now, in this window you should see an icon for "Local Area Connection" and "Local Area Connection 2" for both of your NIC's.
2. Next, you will want to right click on the Network Area Connection icon that connects to your cable modem, and once again select "Properties" from the drop down window. That will open up a window that looks like this:
3. Now, you should notice at the top of the window there are 3 tabs. The tab furthest to your right is the "Advanced" tab. That is where we will want to go next. Click on the Advanced Tab and it brings you to this part of the window:
4. As you can see, the box next to "Enable Internet Connection Sharing for this connection" is checked, however on your computer it will not be checked. Simply check the box and hit "OK" to share your connection through this NIC.
5. Now, double check the properties for your other NIC (connected to your LAN) to ensure that they are setup correctly to use ICS. At the "My Network Places" Window, Right click on your "Local Area Connection 2" Icon and select Properties from the drop down menu. This will bring up a window that looks like this:
Now, to check the TCP/IP settings, Simply double click on the "Internet Protocol (TCP/IP)" line, or highlight it and then click the "Properties" button beneath it. This will bring you to this window:
Your TCP/IP Properties should look exactly like this as well. If they do not, then there is a problem somewhere.
Now, to get your Client computers up and working, here is how you do it. Go to a command prompt, if you're using Windows 2000 or Windows NT, type "ipconfig" at the prompt (if you're using any version of Windows from the Win9x family, go to Start/Run and type "ipcfg" and do a renew from the window). It should display something like this:
Now, at the prompt type "ipconfig /renew" and it should renew the Adapter to try and obtain an IP address from the DHCP server that is running on your host computer. You should get something like this:
And now you're ready to surf the net, get e-mail, instant message, idle in IRC, or play your favorite online games from more than one computer on one broadband connection! Any Questions, send me an and I'll try to help you out as best I can.
