Component Ping on Windows

Can anyone tell me why my WHY DOES THIS NEVER RUN section below does run?  I
want to ping multiple hosts (>1000).  I'm using this to make sure customer
devices that we manage are available.  Using the below, it cycles through
all the hosts but then just sits there.  Also,  many of the pings with this
program fail but if I ping them from a dos prompt they respond just fine.
Any assistance will be greatly appreciated.  Thanks!
