Win32::OLE -remote access to WMI

[svar]

I need to access the WMI remotely and get a few attributes
I found the following script in

http://www.windowsitpro.com/Files/07/20138/Listing_01.txt

use vars qw( $Log $Message $Name $Value );
use strict;
use Win32::OLE qw( in );
my @OS_TYPE = qw(

);
# BEGIN CALLOUT A
my $Class = "Win32_OperatingSystem";
(my $Machine = shift @ARGV || "." ) =~ s/^[\\\/]+//;

# next is the part that fails
my $WMIServices = Win32::OLE->GetObject(
"winmgmts:{impersonationLevel=impersonate,(security)}//$Machine"
) || die "$!" ;

...

I call the script with
perl script.pl 10.100.65.68
(ip of the remote),
but it dies on the last statement -without any error messages. Anyone know what could be wrong here?
