title: windows bat file: undo NET USE
body: <p>In a batch-file I use the following syntax to map a network drive:</p>
  
  <p>NET USE N: \\someserver\somedirectory.</p>
  
  <p>While this works fine, it also gives an error if the letter n is already used. Is it possible to suppress this error message?</p>
  
  <p>Also, is there a way to unmap a network drive?</p>
  
  <p>I imagine something like:</p>
  
  <p>NET UNUSE N:</p>
