Problem password request shared folders

[DMD]

THANK YOU FOR YOUR SUGGESTION! 
I also found a tool (Link Shell Extension), to create the junctions to the folders, which acts from the context menu. http://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html#contact

Perfect no password and I seem to have everything more in order, with this system I can have endless folders and without any request for credentials.
In my case I inserted in the main folder giving it the name "CONDIVISIONI_MULTIMEDIALI", and I added more than 50
subfolders, for sharing just share only the main folder.



Thank you for the brilliant solution you gave me.
