Associate PID with ICMP Request in Windows?

["Megan Kielman" <megan.kielman () gmail com>]

On a  Windows system, how would I go about determine which PID is
issuing an ICMP Echo Request? I read an article about the ping message
and it said that on Windows, the Identification field always shows 256
whereas other OS's actually show the PID of the process initiating the
ping.

Thanks!
