title: Can't connect to Sql Server database using JDBC
body: <p>I'm trying to make a connection to an already existing database in SQL Server 2012n with Netbeans 8.</p>
  
  <p>Using the connection wizard I select Sql Server 2012 and enter the credentials and fields.</p>
  
  <p>However I get the message that a connection cannot be established.</p>
  
  <p>You can see screenshots of the entered fields:</p>

  <p>I also tried using "localhost" instead of "STIJN" this didn't work. I also tried with the default port "1433". Also didn't worked, however what port should this be? Where can I see what port I'm using? Maybe the error lies in the port, otherwise I wouldn't know where I made a mistake.</p>
