When navigating to http://(FQDN)/AAPS/login.aspx the following error occurs.
HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.
Detailed Error Information
Module IIS Web Core
Handler Not yet determined
Error Code 0x8007000d
This error occurs when there is a problem reading the configuration file for the Web server or Web application. IIS does not have the URL Rewriting module installed, so the section of the web.config will cause IIS to give HTTP Error 500.19 with error code 0x800700d for any page.
Simply resolve this, simply install the URL Rewriting module, which can be downloaded here http://www.iis.net/download/urlrewrite (this may require a restart of IIS or your machine) and will resolve the issue.
Password Server v2.x - newer.
