For example if you're able to PING a remote computer, then you know that your computer is able to talk to it and that it's able to talk back to you. The IPCONFIG command is handy for finding out information about your computer's TCP/IP information, such as your IP address.
In order to access these utilities you must use the MS-DOS command prompt. To access the command prompt, from the Run... command under the Start menu, type CMD and press Enter. To exit the command prompt, close the window or type EXIT and press enter.
