 * Checking the state of your TCP/IP protocol **

 To test your TCP/IP protocol and repair it if necessary, there are two low level commands provided by Windows; these are:-  Ping and Netsh. The first one can be used to check that your TCP/IP protocol is functioning, and the second is a scripting tool that can be used to rewrite two registry entries to fix the TCP/IP protocol. How to use these two commands below:- If your ping is successful, you will see 4 replies. If you see a local host unknown message, then you need to repair your TCP/IP protocol. To do this-:
 * 1) Hold down the **[Windows]** key and press **[R]** to open a run box. Type in **cmd** and press **[Enter]**.
 * 2) In the command prompt window, type **ping localhost** and then press **[Enter]**. Alternatively, you can type **ping 127.0.0.1** to test the loopback address (if using IPv6, type **ping ::1**).
 * 1) In your open command prompt window, type :- **netsh int ip reset c:\resetlog.txt** and press **[Enter]**.
 * 2) Restart Windows to complete the repair.
