title: Cannot connect remotely to a SQL Server named instance
body: <p>I have SQL Server 2008 installed on a VM in which I have three instances:</p>
  
  <ul>
  <li><em>server name</em></li>
  <li><em>server name</em>\DB1</li>
  <li><em>server name</em>\DB2</li>
  </ul>
  
  <p>From my local machine I am trying to use Management Studio to connect to those three instances. I can connect without any problem to the <em>server name</em> instance but when trying to connect to the other two it fails with error:</p>
  
  <blockquote>
    <p>"A network-related or instance-specific error occurred while
    establishing a connection to SQL Server. The server was not found or
    was not accessible. Verify that the instance name is correct and that
    SQL Server is configured to allow remote connections"</p>
  </blockquote>
  
  <p>I have already verified that all three instances allow remote connections, the port is the default one on all three, all of them have the TCP/IP protocol enabled and I can connect locally to all three by using the <em>server name</em> \ <em>instance name</em> format.</p>
  
  <p>What else could possibly be preventing me from connecting to the two named instances?</p>
  
  <p>Thank you.</p>
