Question : access denied to a vista pc where i have shared folder.

I have a pc with vista, i have shared a folder called SCAN.
when i try to connect to this pc (using IP and netbios name) it say "Access denied" or "the network path is not found"...
I'm sure that IP is right.
Also if I try to connect directly to the folder \\myip\scan
firewall is disabled

I have activate all necessary reading all documents in the web.

Some suggest?
thanks
Paolo
