title: Database error occurred (SQL error 18054) when mapping local directory in TFS
body: <p>I'm using VS2010 as a client for a TFS instance.  I created a workspace, and need to map a TFS directory to a local directory - let's call the local directory "<strong>D:\aaa\bbb\ccc\ddd</strong>".  When I navigate to "Manage Workspaces"  and click "edit" to change the local directory to this path, I am presented with the following error: <a href="https://i.stack.imgur.com/9YV5K.png" rel="noreferrer">1</a></p>
  
  <p>This error occurs when I try to map:  "<strong>D:\aaa</strong>", "<strong>D:\aaa\bbb</strong>", "<strong>D:\aaa\bbb\ccc</strong>".</p>
  
  <p>Now, if I create a folder called:  "<strong>D:\aaa\bbb\ccc1\ddd</strong>", the mapping works, and I do not receive this error.</p>
  
  <p>Can anyone help?  I've been pulling my hair out for about a day over this.</p>
  
  <p>Thank you.</p>
  
  <p>[EDIT01:  I tried mapping all other folders under the D:\ drive, and only one other folder fails the mapping.  I receive the same error as with "<strong>D:\aaa\bbb\ccc\ddd</strong>" ]</p>
