title: Adding TableAdapter throw me a failed to to open connection
body: <p>I try to create a TableAdapter in visual studio, I pass all steps of the wizard and when I end, it tries to create the TableAdapter and give me an error. It's my first time trying to create a TableAdapter so I may miss something really obvious.</p>
  
  <p>My setup</p>
  
  <ul>
  <li>Visual Studio 2010</li>
  <li>My instance is on <code>\\VMDEVCIAQ\NMPUTIL</code></li>
  <li>My connection string is <code>Provider=SQLNCLI10;Data Source=VMDEVCIAQ\NMPUTIL;Persist Security Info=True;Password=Secret;User ID=Secret;Initial Catalog=NMPUTIL</code></li>
  </ul>
  
  <p>Error message</p>
  
  <p><code>"Failed to open a connexion to the database, error 26 error locating the server/instance specified"</code></p>
  
  <p>What I tried</p>
  
  <pre><code>- portqry.exe -n VMDEVCIAQ -p UDP -e 1434 
  </code></pre>
  
  <p>and it gave me a positive answer. So it's not a firewall problem or SQL Browser service not running. </p>
  
  <p>I know the connection string work since in the connection wizard it says connection successful.</p>
  
  <p>Any idea why visual studio is being mean to me ?</p>
  
  <p>Cheers</p>
