I have a MacBook Pro (OS X 10.8.4) and a Windows 7 Ultimate machine. I can't connect to the latter because of incorrect password or login. I tried to create several users on Windows machine and even created quest user and it also does not work. On the Windows machine:
- network discovery turned on
- file and printer sharing turned on
- public sharing turned on
- firewall switched off
Also I can connect to Filezilla's FTP server and RDC Mac client works fine but SMB doesn't want to work at all.
