Khi kết nối thì báo lỗi như sau:
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)
mong các pro giúp... Mói cài lại cái SQL, thư kết nối thì bị lỗi
