Problem connecting to sql server express edition RRS feed

  • Question

  • I have difficulties connecting to my SQL Server Express edition.

    The Server and its SQL Browser are both running and named pipes are enabled,

    even if I am not sure why it would return such an error since I only try to connect to my localhost.


    My connection string is currently:


    Data Source=localhost\SQLEXPRESS;Integrated Security=True;Pooling=False


    the initial catalog is not yet set, because I try to use the connection (System.Data.SqlClient.SQLConnection) to create a new database by ddl.


    The resulting error is: 

    provider: Named Pipes-Provider, error: 40

    Connection to SQL-Server could not be established


    Any suggestion greatly appreciated.
