Mount Windows folder 

1. First, edit your /etc/hosts file and give the Windows machine a name you want to mount from: 192.168.1.2   pootie
2. Next, install the samba and smbfs packages using your method of choice. (e.g. synaptic || Ubuntu software center) Create a directory where the share will appear on your local filesystem. $ sudo mkdir /mnt/music
3. Edit /etc/fstab and add a line for the mount. Here "pootie" is the name of the machine and "music" is the name of the share.//pootie/music  /mnt/music  cifs exec,credentials=/etc/cifspw 0 0
4. Create a password file /etc/cifspw with the login credentials for your Windows account. (if your windows account is going to change you'll need tp change that either):username=Jason
   password=ImNotGonnaTellYouThat
5. And secure the file: $ sudo chmod 600 /etc/cifspw
6. then excute the followed: $ sudo mount -a
