   ping <ServerName>

   where ServerName is the name of your SQL Server.

   If the SQL Server is online, verify that you are connecting to the correct port.

   If your SQL Server is not running on the default port (1433), type the following in Server on the Project Configuration dialog box:

   <ServerName>,<Port>

   where ServerName is the name of your SQL Server and Port is the number of the port on which your SQL Server is running.
