PersistClassID is returned by GetClassID. It defines a registered COM class that provides the streaming methods for this object. A NULL_GUID defines that there is no class available. In this case the GetClassID returns E_FAIL. 

You can register this class (TJwServerAccessControl) as an official COM object. To do so you need to provide the class in a COM dll that is registered properly.
