I'm pretty sure that my computer or server is name is NUNA but it doesn't connect and I get this error. I have tried to stop SQL Server Express in Windows Services, but it doesn't show the SQL Server Express
Did you try restart SQL Server service or try with "."?

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.

I installed SQL server 2014 newly. When I am opening SQL Server Management Studio and giving localhost as server name then I am getting error 40 i.e.
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)
While installing the SQL Server there were no instances given by me so there is only default instance. I read many other posts here in Stack overflow and also found that there is no service like MSSQLSERVICE in my services that I can run..
I am not sure what has gone wrong.
