track down source of interference? package method works in one, not in another?

track down source of interference? package method works in one, not in another?

(OP)

Unfortunately, in a situation where I cannot post the full code. So, I have to stick to sanitized examples and philosophy.

Windows 32bit perl running on Windows 2008 R2 (64bit). Nearly everything works, except....

CODE

#!perl
use strict;
use Win32::Lanman;
use Data::Dumper;

my $arrayRef = [];
unless (Win32::Lanman::NetLocalGroupEnum('',$arrayRef);

print "GROUPS: " . Dumper($arrayRef) . "\n"; 

I our main application code, the 7th line does not populate $arrayRef and an error code is set. If I pull that 'logic' out of the main application code and run it as a little snippet, it works fine.

I'm a Linux/UNIX guy, mostly. This Windows stuff is voodoo. What would make that call to NetLocalGroupEnum behave differently in the main app and in my snippet?

Ideas?
Ways to track this down?
'Seems something is getting over ridden, but, what? How to tell?
I know there are some oddities with how Windows handles 32bit vs 64bit perspectives on the registry. Is there anything like that going on with the Lan Manager?

TIA

'hope this helps
