PathPing

PathPing is a command-line route tracing tool that combines features of the tools Ping and TraceRt with additional information. PathPing sends packets to each router on the way to a final destination over a period of time, and then computes results based on the packets returned from each hop. PathPing shows the degree of packet loss at any given router or link, allowing you to pinpoint which routers or links might be causing network problems. Start PathPing from a command prompt rather than from Windows Explorer to see the resulting display.
