title: Issues with .bat sharing Folder on Network (net share)
body: <p>I'm having an issue with net share. Basically if it's a new share it works perfectly. However existing shares I cannot modify the roles with net share?</p>
  
  <p>Steps to reproduce my problem (As I am having a hard time putting it into words)</p>
  
  <p>Step 1: Create a new folder at <code>C:\My Test\StackOverview</code></p>
  
  <p>Step 2: Run the following .bat</p>
  
  <pre><code>net share StackOver /DELETE
  net share StackOver="C:\My Test\StackOverview" /GRANT:Everyone,READ
  </code></pre>
  
  <p>Result: When user "testuser" attempts to access files it works perfect.</p>
  
  <p>Step 3: Now create a new folder at <code>C:\My Test\NotWorking</code></p>
  
  <p>Step 4: In Windows (Not with a .bat) right click the folder and Share this folder with specific people but insure "testuser" isn't one of them</p>
  
  <p>Step 5: After the folder is shared run the following .bat</p>
  
  <pre><code>net share NotWorking /DELETE
  net share NotWorking="C:\My Test\NotWorking" /GRANT:Everyone,READ
  </code></pre>
  
  <p>Result: "testuser" cannot access this folder. It says he doesn't have the correct permissions. I would expect the script to work either way? Any help would be appreciated. </p>
  
  <p>Thanks,
  Matt</p>
