How to Troubleshoot Ping
The DOS "Ping" command lets you send a packet to another network computer. The ping command is used to troubleshoot network issues. Identify if you have a connection issue, if TCP/IP settings are bad or if the network router is not running properly. The ping command is included with each version of Windows, so network administrators can identify issues on any Windows desktop.

Click the Windows "Start" button and type "cmd" into the text box. Press Enter to open the command prompt. Type "ping computer" where "computer" is the computer name you want to ping. Press Enter.

Check your network TCP/IP settings. Type "ipconfig" in the command prompt and press Enter. The returned information should display an IP address. If you do not have an IP address assigned, type "ipconfig /renew" to renew an IP address with your network server.

Check your Ethernet cable, if you are hardwired to the router. If you have a bad cable or connection, the ping command fails. If you have an extra cable, swap out a new cable for the current one to ensure that the issue is not with the cable.

Ping an Internet domain. Pinging an Internet domain lets you identify if an issue is caused by your router. Type "ping domain" into the prompt. The router routes traffic to the external Internet cloud. If you can ping an internal computer, but you cannot ping the Internet, the problem is a bad router or router configuration.

Ping the "localhost" address. Pinging localhost tells you if the problem stems from your network card. Type "ping 127.0.0.1" into the command prompt. If the ping fails, you have a bad network card or the network card's drivers are corrupted.
