title: Make SQL Server 2008 Instance invisible (nonpublic)
body: <p>We need to make some instances of our SQL Server invisible, so you can't view it from SQL Server Management Studio "Browse for servers" screen but you can connect to it if you know its instance name...</p>
  
  <p>Also prevent any possibility of getting the list of the other instances from inside an instance that you are connected</p>
  
  <p>Any ideas?</p>
