Answer :

First check if SQL Server is up and running on the database server.

If yes, then check if Shared memory/TCP-IP/Named pipes protocol is enabled on SQL Server. You can check that in SQL Server configuration manager. If it is not, then you have to enable it and then restart SQL Server service.

Also if you are using SQL login to connect to database, then you have to check if mixed mode authentication is enabled on SQL Server. To check that connect to SQL Server and right click on instance and go to properties -> security tab -> check if mixed mode authentication is enabled or not. This will again require SQL Server service restart to get the change reflected.

Check these 3 things first and let me know if it does not resolve your problem.
