Can you ping the server from the client?
What's the client PC's IP before you establish the tunnel? Is it already on the same subnet as the server?
What error do you get when you run
net use \\192.168.1.2\myshare
from Windows Command (obviously replacing \\192.168.1.2\myshare with your own server details)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
