"Ping" can be useful to troubleshoot network connectivity quickly. Ping will let you send a request to a server to say "Please reply" and the server will send you a sort of "Hello." Think Ping > Pong.
- In Windows Vista, it is much the same as previous Windows OSes. From a run command you can type "CMD".
- In the command prompt that opens, type "ping acme-hosting.net" or ping whatever server you wish.
You will either receive a reply, no reply, or some variation.
