PINGPing is the most important troubleshooting command and checks the connectivity with other computers. For example, your system’s IP address is 10.10.10.10 and your network server’s IP address is 10.10.10.1 and you can check the connection to the server by using the ping command in the following format.
At DOS command prompt, type ping 10.10.10.1 and press Enter
When you receive the response from the server then the connectivity is ok and if you get the error message like this means to get “Request time out” so that there is a problem in connecting to the server.
