title: fstab mount network share with guest
body: <p>when I mount my network share on Debian 9 with command line it goes with success:</p>
  
  <pre><code>    mount -t cifs -o guest //Server/Share /mnt/sharefolder
  </code></pre>
  
  <p>But when I add an entry to /etc/fstab:</p>
  
  <pre><code>    //Server/Share    /mnt/sharefolder    cifs    guest    0    0
  </code></pre>
  
  <p>There comes the error: failed(Result: exit-code) and status=1/FAILURE</p>
  
  <p>What is my mistake?</p>
