Use of Ping

If a machine cannot mount a remote file with the net use command, verify that the path name to the file system you want to access has been typed correctly. Then use the ping command.

If a user is copying files to or from a network drive and the process stops before it is completed, use the ping command.

If a machine has been receiving a license and cannot receive a license when it is turned on or rebooted, and instead receives error messages, use the ping command.
