Problem with NET::PING

[VeeraRaju_Mareddi]

Dear All 
I have a small with NET::PING.I hope its working by following command.
USE NET::PING;
But I am Not able to check remote connectivity of a host ("HOTNT002")
through this NET function...I am sure its reachable by system ping
command(Windows NT 4.0)..

My Perl Code is given Below:

use net::ping;

$p = Net::Ping->new();

$host="hotnt002";

print "$host is alive.\n" if $p->ping($host);

$p->close();


Ur Help is Greatly Appreciable
Thanx in Advance..
