that depends on what you are referring to.
Are you looking to access files that are on your linux box from your windows machines? If so, you need samba server on the linux machine.
Are you looking to access files that are on your windows machine from your linux machine? You need nothing. just mount the share as a cifs filesystem.
Are you looking to ssh into the linux box from windows? look at installing an app like putty on your windows machine
You need to determine exactly what you wish to do and ask more directed questions to get a good answer.
