How do I fix the error 'Named Pipes Provider, error 40 - Could not open a connection to' SQL Server'?

Question

I can\'t seem to connect to my database from a site. I get this error:

Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

Answer 1

I had the same problem. I use the MSSQL Server Management Studio 2017 and solved this problem using these steps:

1. Check for working fine SQL Server Services services or not.
2. Also check for working in good condition SQL Server (MSSQLSERVER).
3. Also check for working fine SQL Server Browser.
4. Restart SQL Server (MSSQLSERVER)

and fixed it.
