title: SQL Server 2014 Express on Windows 10
body: <p>I've downloaded and installed SQL Server 2014 Express on Windows 10, I've been through this loop at least 3 times now. The installation completes without warnings or errors. I have chosen to use Window authentication. I'm trying to use HeidiSQL to connect to SQL Server. I already have MariaDB installation and am able to connect to that using HeidiSQL.</p>
  
  <p>When I connect to MariaDB I am able to select Databases from the drop down combo, but not for SQL Server. I don't seem to be able to connect with HeidiSQL.</p>
  
  <p>In HeidiSQL, the settings are:</p>
  
  <ul>
  <li>Network type: Microsoft SQL Server (TCP/IP, experimental)</li>
  <li>Hostname / IP: 127.0.0.1</li>
  <li>Ticked checkbox 'Use Windows authentication'</li>
  <li>Port: 1433</li>
  </ul>
  
  <p>I can't select a Database, if I click on the Open button after a while it comes up with:</p>
  
  <blockquote>
    <p>SQL Error(17): [DBNETLIB]ConnectionOpen (COnnect()).]SQL does not exist or access denied SQL Server does not exist or access denied.</p>
