Lots of possibilities; my first instinct would be to shut off dual interface support to force VFP to to use IUnknown to explore the interface. What flavor ofVC++ COM implementation was used? I've got more than passing familiarity with ATL implementation...
You can explore the COM component in detail using OLE View; it should show you all the interface definitions if you view the server's embedded TLB details.
