I have a web application built in .Net 3.5. Due to an upgrade to IIS7.5, I have recomplied the application using .net 4.0. Everything seems to be fine when debugging via the development server however when using IIS, I get the following error when trying to access an aspx file.

HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. Detailed Error Information Module StaticFileModule Notification ExecuteRequestHandler Handler StaticFile Error Code 0x80070032 Requested URL http://localhost:80/pij/service/Gateway.aspx Physical Path C:\inetpub\wwwroot\pij\service\Gateway.aspx Logon Method Anonymous Logon User Anonymous

Prior to changing the application's app pool to v4.0 Classic I was getting the following.

HTTP Error 500.22 - Internal Server Error An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.

If anyone has any ideas how I can fix this, I'd be most grateful thanks

  • 3 - yes i meant that. Please try also to see if by any change you have aspx in the mime types... if so remove it as this is not a static file...
