    Error: Failed to generate a user instance of SQL Server...

    Hello

    I am really terribly stuck trying to work together with SQL and Visual Studio together, using ASP and AJAX together....however, the problem is not the programming...its to do with SQL Server.

    When I try to run my .aspx file in the browser (which includes a 'create new user' login control) through Visual Studio 2005, I get an error saying: "Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed".

    Error Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

    SQLExpress database file auto-creation error:
    The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:
    1) If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist.
    2) If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database.
    3) Sql Server Express must be installed on the machine.
    4) The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.

    -------------------------------------------------------------------------

    I have installed....uninstalled....reinstalled SQL server uncountable times now....but still get the error.....

    I have tried a few things when I search about this on Google....but none of those things seem to work.

    I am really stuck. Please any help/suggestions would be much appreciated.

    Thanks

    Well, first of all, you are posting in a MySQL forum, inappropriate for questions regarding SQL Server.

    But second of all, this site is not the best place to post SQL Server questions.

    Try http://www.SQLTeam.com -- that site specializes in SQL Server and only SQL Server.
