Is there a way to only share folders with certain computers on the network?

I'm wondering if there's a way to share certain resources over a network to specific computers only. Wired and wireless, without a domain controller.

Nope, not what I'm looking for. I've been over these tutorials scouring the forums for any scenarios that match mine. Thanks for your time though.
I know how to allow or deny users and such.
What I'd like to do is share a folder with two computers on the network. There are numerous computers on the network, but only these two need access, the rest NEED to be restricted access from this folder.
