If you have registered and loaded the licenses successfully, but still DECnet-OSI won't start, you might have too few license units for the system type. Can you tell a bit more about your system and the licenses you are trying to use. THat would be helpful.

I'm been playing with Tru64 and I managed to get DECnet installed...some common library files referred to DECNET-OSI-END and DECNET-OSI-EXT, are these the correct licenses, or need I load others?
