file share problem

[Qutab]

Mery pass aik PTCL ka switch & router laga hoa hy, ab us k andar jo bhi PC lagy hoy hain. vo tamam PC aik dosry sy share hain.

for example PC (a, b, c, d) 4 PC hain.
ab main chahta hon k a se d ko koch share kron, to jo file main share karta hon vo b aur c bhi dekh lety hain.
Kiya aisa koi tarika hy k jis ko main share kron sirf vo hi dekh saky. aur koi bhi nai.
