title: Can't remove workspace from TFS
body: <p>I want to add my project from Visual Studio 2012 to my TFS server, but it says the path is already mapped for workspace pc;administrator (this is a <em>local workspace</em>).</p>
  
  <p>I have tried the command tool <code>tf</code> but it says that there are no workspaces, so I can't delete the workspace that is conflicting.</p>
  
  <p>I'm running Windows 8 with Visual Studio 2012. TFS is on a windows server 2012.</p>
