I got the following error while trying to make a test WCF project on VistaServer ErrorHTTP Error 500.19 - Internal Server ErrorDescription: The requested page cannot be accessed because the related configuration data for the page is invalid.

This seems similiar to an issue I had. It turned out to be a security setup issue. Check the web application folder permission and make sure the following users and groups are included \ASPNET and \IIS_IUSRS and \IUSR.
