title: SQL Server 2012 connection issues in Visual Studio 2012 Server Explorer
body: <p>I am trying to connect to SQL Server 2012 installed on Windows Server 2012 through Visual Studio 2012 but keep getting an error 25 connection string is not valid message when trying to connect through server explorer. </p>
  
  <p>As far as I am aware it is sharing the same IP address as the main server. I am not connected to the domain but have checked that remote connections are enabled and port 1433. I can also connect to the main server. </p>
  
  <p>I am new to SQL Server so any advice is greatly appreciated. Thanks</p>
