Even if you can successfully connect using SQL Server Management Studio, DbVisualizer may fail to connect since it connects using a different protocol.

Please make sure that TCP/IP is enabled for the database and that it listens on the port you are connecting to (please refer to Configure Client Protocols for details). You may also have to Configure the Windows Firewall to Allow SQL Server Access.
