Por supuesto ya he buscado una respuesta en la WEB y he hecho una búsqueda en el foro, tampoco he podido obtener una solución traduciendo algún código encontrado de C++, ni mucho menos desde VB.net. También alterando las llamadas a diferentes aproximaciones posibles pero no he podido pasar mas allá del error de sistema 87 "A parameter is not valid" devuelto por la función.
Puedo obtener correctamente las ACEs explicitas en Win7 y WinXP SP2 y mi intención es obtener información acerca de las ACEs heredadas.
Código:

Type GENERIC_MAPPING
'The GENERIC_MAPPING structure defines the mapping of generic access
'rights to specific and standard access rights for an object. When a
'client application requests generic access to an object, that request
'is mapped to the access rights defined in this structure.
GenericRead As Long
'Specifies an access mask defining read access to an object.
GenericWrite As Long
'Specifies an access mask defining write access to an object.
GenericExecute As Long
'Specifies an access mask defining execute access to an object.
GenericAll As Long
'Specifies an access mask defining all possible types of access to an
'object.

Private Type GUID
'GUIDs identify objects such as interfaces, manager entry-point vectors
'(EPVs), and class objects. A GUID is a 128-bit value consisting of one
'group of 8 hexadecimal digits, followed by three groups of 4 hexadecimal
'digits each, followed by one group of 12 hexadecimal digits. The
'following example GUID shows the groupings of hexadecimal digits in a

Estaría muy agradecido si alguien pudiera ayudarme a salir del estancamiento.
Desde ya muchas gracias.
