I'm using Microsoft SQL Server Management Studio from last one month that is evaluation period software. I'm not able to login in management studio. when I enter my user name and password it gives the error:
TITLE: Connect to Database Engine
Cannot connect to sony-PC
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: 2)
How can I take backup of my database?
