I deployed an ASP.net MVC 2 application on my Windows Server 2008 IIS7 server

I deployed an ASP.net MVC 2 application on my Windows Server 2008 IIS7 server and it bombs out reporting:

Login failed for user ‘NT AUTHORITY\ANONYMOUS LOGON’.

I have SQL Server authentication enabled on the server and I have created a login for the database that I am trying to reach. I don’t understand why the ‘NT AUTHORITY\ANONYMOUS LOGON’
credential is being used. This must be the context in which the application is running (application pool). I assumed that the application would just use the credentials specified in the connectionstring. How can configure IIS7 and/or ASP.net to just login using the user and pass provided in the connection string specified within the web.config?

Thanks a ton.

I’m pretty sure the problem is at the SQL Server or with my IIS configuration. The application works from my development machine.

Connnection String :

connectionString=”Data Source=servername;Initial Catalog=TestPortal;User Id=username;Password=password;”

    By default Entity Framework connection string has:

    Integrated Security=True;

    This should be removed from both the asp.net membership provider connectionstring as well as from the entity framework’s generated connectionstring.
