Samba file share with a Windows Server

You may need to install smbfs:

sudo apt-get install smbfs 

I assume samba is already installed, if not:

sudo apt-get install samba 

Create directory to mount 

$mkdir -p /mnt/win

Mount windows server to the newly created directory
$mount -t smbfs -o username=winntuser,password=mypassword //windowsserver/sharename /mnt/win

(Source) 

Next create the password file /etc/sambapasswords:

cat > /etc/sambapasswords 
username = winntuser
password = mypassword
make sure that only root have access to it

chown root:root /etc/sambapasswords
chmod 600 /etc/sambapasswords 

Add an entry to your /etc/fstab: 

//windowserver/share /mnt/win smbfs

auto,gid=users,fmask=0664,dmask=0775,iocharset=iso8859-15, credentials=/etc/sambapasswords 0 0
