I installed Microsoft SQL Server 2016 Management Studio on my PC, and when I try to connect to a server, it shows this error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
I don't know what should be the server name. How can I connect to a server?
Run the command SQLCMD -L in a command prompt and you will see your available server names.

Take a look at Administrative Tools\Services and restart your process SQL Server (SQLEXPRESS).
Check if the Sql Server service is started in Administrative Tools -> Services.

telnet localhost 1433
