Description:
------------
Can't iterate through list of NT Group memberships.
Same code (as VBScript) works in asp page (lists group names.)

Reproduce code:
---------------
try {
 $objUser = new COM("WinNT://myDomain/aUserAccountName");
 foreach ($objUser->Groups as $grp) { 
  echo $grp->Name; 
 }
 $objUser = null;

} catch (Exception $e) {
   echo 'Caught exception: ',  $e->getMessage(), "\n";
}


Expected result:
----------------
List of groups that the account is a member of.

Actual result:
--------------
Caught exception: Error Member not found.  

But ->Groups _is_ the collection of groups...

(Have looked at Bug #25759 COM Instantiation causes Script to fail silently)
