Windows Networking -- Mega flaw here

I don't want to allow smart TV direct access to drives on the Network server - the windows machine should be able to allow access to other machines from its own shared resources.

Not necessarily. What makes you believe that such "transitive" sharing should be permitted?

Ability to access restricted resources of the network server is the privilege the server issues to its selected clients. It is a matter of server's decision: which clients should be allowed access to which resources.

Just because server decided to give such access privilege to a specific client does not mean that server wanted to permit this client to distribute this privilege further to whoever/whatever that client pleases. That would constitute a rather loose approach to access control.

Of course, if you really really really want to set up your local network's access control in that way - then you might want to have it in Windows, as an option (!). But it is definitely not acceptable as a default access privilege distribution model. So your claim that it "should" work that way and/or that it is somehow "natural" does not hold water. "Mega flaw"? Not really.
