Answer 1

Try using code below to open the connection.

Try
        Dim objconnection As SqlConnection = New  _
            SqlConnection("Server=localhost;Database=DATABASENAME;" & _
                          "user ID = YOURUSERID; password = YOURPASSWORD;")

        objconnection.Open()
        objconnection.Close()

        MessageBox.Show("Database Connection Success")
Catch ex As Exception
        MessageBox.Show("Database Connection Error: " & ex.Message)
End Try

Answer 2

Check if SQL Server is configured (via SQL Server Configuration Manager) to accept remote connections.

Also, you may need to check the Connections property page for your database in Management Studio, as well as firewall settings: http://blogs.msdn.com/b/walzenbach/archive/2010/04/14/how-to-enable-remote-connections-in-sql-server-2008.aspx
