$ sudo apt-get install smbfs
2. Create a directory where you will mount the Windows shares:
$ sudo mkdir /media/mount_point
3. Mount the Windows shares (assuming my username is "abc123" and my password is "passwd"):
$ sudo mount -t cifs //path_to_the_server -o username=abc123, password=paswd /media/mount_point
Note: In order to have read/write access to the files on the server, access them from your local machine as root.
