Hi,

I have a little script, that first checks the availability of a DFS Cluster here. The cluster has an alias name which is used to map drives etc., so I'm using that alias to ping it for availability.
I can ping that alias in a dosbox.
When I use a normal servername to ping, it works with the script.
When I use the clusteralias, it works from one machine, from another not.

This is the code I use:

use strict;
use warnings;
use Win32::FileOp;
use Term::ReadKey;

my $pinghost="dfsalias";

print "Checking avalability of destination...";
my $p = Net::Ping->new();
if (!$p->ping($pinghost)) {
	print "\ncan't reach $pinghost: no network? Exiting!\n";
	print "\nPress any key to continue...";
	ReadMode('cbreak');
	my $key = ReadKey(0);
	ReadMode('normal');
	exit;
}

Any ideas? I know it must have to do something with that alias...

Lars
