  <p><strong>With System.Data.SqlClient</strong> and SqlConnection.Open() everything <strong>work</strong> fine I'm able to connect and execute SQL scripts (with and without Windows Authentication).</p>
  
  <p>What I tried so far:</p>
  
  <ul>
  <li>I checked in MS SQL Management Studio in Conncetions "Allow remote
  connections to this server" (Checked)</li>
  <li>In SQL Server Configuration Manager on my SQL server TCP/IP protocol is enabled</li>
  <li>I tried to connect with turned off firewall and antivirus protection</li>
  <li>I tried with new Logins (with System.Data.SqlClient.SqlConnection it work)</li>
