SQL Server Connection Problems

Posted on 2011-04-18

I just installed MS SQL Server Express.  When I open the Management Studio, I can't get it to connect.  I get this error:

Cannot connect to instance.

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 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)

Does anyone know what I should do?

    Accepted Solution


    Most likely you are not using the correct instance name

    Try using your PC name + Your instance name


    If you cant figure out you instance name, check in SQLO Server Configuration Manager

    Assisted Solution

    Check the instance is started. Go to SQL conf. Manager - the sAme picture as above.

    Then check the instance as above. And of course make sure you use the right credentials. Either SQL authentication or windows authentication.

    By having this verified you should be ae to access the SQL instance.
