If you don’t have your TCP/IP (Transmission Control Protocol/Internet Protocol) installed. These protocols facilitate network and Internet communication, so you’ll need to install them.
Click Start and Control Panel, then double-click Network Connections.
Right-click the connection to your network and click Properties, then check the list of items in the This Connection Uses The Following Items field for an Internet Protocol (TCP/IP) entry.
If it’s not there, click the Install button below, then double-click Protocol. Now find TCP/IP (may appear as Microsoft TCP/IP version --) in the Network Protocol field of the Select Network Protocol dialog, click to select it, and click OK.
If after installing TCP/IP you’re still not getting a response from PING, check your physical connections (make sure your network cable plugs are properly seated in their ports) and then check to see if you have a firewall running that isn’t allowing your system to access the Web.
Many firewalls can be configured to refuse access without inquiring of the user whether they desire it. If that’s the case, scan the program’s interface or check its Help files for the menus and commands you can use to configure your firewall to allow outbound access. (These vary from program to program.)
