You’ll want to make sure “Obtain an IP address automatically” is the choice with the circle filled in with black. And, as the pink suggests, you do not want any numbers in the IP address and Subnet Mask filled in. Once you set those options, click the “OK” button at the very bottom; wait for Windows to copy the correct files; then restart.
Your client computer will now look for the server. The server will then assign your client computer an IP address, and tell that client computer to ask the server for any Internet information. This way, your dial-up or cable information is now shared.
Next up, go back to the server and go to the next page.
