Error in 3-Layer Project RRS feed

  • Question

  • Hi

    I have a 3-Layer project, I want to add a user. I use Connection String in web.config and it seems that everything is ok

    but when i run website i get this error.

     What should I do???!!!


    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)

  • Sounds like you need to configure SQL Server to allow remote connections. You'd use SQL Server Configuration Manager to do this. SQL Express, for example, isn't configured to allow remote connections by default.

    I'm going to move the question to a forum for ADO.NET SqlClient for best results, and if you're sure that you have SQL Server configured correctly, it might be best to repost to the ASP.NET forums (I can't move it there directly).

    Cheers, Bob

  • They're here: http://forums.asp.net/. There's a bunch of them, separate from MSDN and TechNet forums, which I why I can't move things there. Don't ask me why they need to be totally separate. :-)
