I can access and read a Samba folder from Windows 7. I've been following some sites instructions:

My Windows 7 is configured like told below:

And my smb.conf has a shared folder, configured for do not require authentication, as the following site says so:

I also tried the following:

chmod -R 775 sharedfolder
chown -R someuser:somegroup sharedfolder
in smb.conf :
   create mask = 0775

But I still get the message that I have no permission to write.
