Network communication test
Use Ping to test the communication between computers on an Internet Protocol (IP) network.
To perform a ping test, open a command prompt on each computer and type ping
<computer_name>, where <computer_name> is the name of the other computer you want to contact.
A successful response shows 4 attempts to contact the computer, lists the IP Address, indicates Packets: Sent = 4. Received = 4, Lost = 0 (0% loss)
, plus timing data. If this is not the case, it indicates that the computers cannot communicate and that you need to resolve the connectivity situation.
NOTE: The ping utility requires that Internet Control Message Protocol (ICMP) is enabled on your network.
