Just started to learn SQL, I can’t start using MS SQL Server. When I try to execute "sqlcmd" on the command line, I get:

HResult 0x2, Level 16, State 1 Named Pipes Provider: Could not open a connection to SQL Server [2]. Sqlcmd: Error: Microsoft SQL Server Native Client 10.0: Error: It was a network connection. Server is not found or not accessible. Check if instance is correct and i f SQL Server is configured to allow remote connections. For more information see SQL Server Books Online .. Sqlcmd: Error: Microsoft SQL Server Native Client 10.0: Login timeout expired.

  • Run sqlcmd /? and see what arguments he needs - renegator

Explicitly transfer the server and login:

 sqlcmd -S (local)\sqlexpress -U sa

    It is very similar to the fact that you are trying to connect to a network instance of SQL Server, on which the SQL Server Browser Service is disabled. If my guess is true, then to solve your problem, just run this service.
