From Net::Ping: croak("icmp ping requires root privilege") if ($> and $^O ne
'VMS');

That $> is a check for euid == 0 (root). The problem is, that on Windows, there
isn't really a 'root' user. ICMP pings are allowed to everyone in the
Administrators group, IIRC. So, the quick fix is to comment the above line out
in /lib/perl5/5.6.1/cygwin-multi/Net/Ping.pm. (Although your script may fail
with a non obvious error if a non-admin tries to run it.) The long term fix is
for cygwin specific logic to be added to Net::Ping.

Max.
