Ping command sends an Internet Control Message Protocol (ICMP) packet to a host and waits for a return
packet, listing the transit time. If there isn't a return packet, Ping indicates that with a Request Time Out
message. The Tracert command traces the route between two hosts and can be useful in determining
where in the route a communications problem is occurring. Windows 2000 provides the
command, which combines the features of Ping and Tracert and adds additional features to help you
troubleshoot TCP/IP connectivity problems.
