On my test setup, I did this by just typing :
smb://
into one of the "Nemo" file browser windows, followed by the URL for the Windows share you were trying to reach.
So, whereas on Windows you would type " \\servername\sharename\ ", in Mint I type " smb://servername/sharename ". There might be better ways, but this always seems to work for me.
Once I found the folder I wanted (my home folder in this case), I dragged it to the 'My Computer" menu on therightleft side of the window and whenever I click on that it auto-mounts the share.... assuming you saved your password when you made the connection for the first time.
