Why do I get "HTTP Error 500.19 - Internal Server Error" when trying to access a GeoStream page?
Issue:
The following is shown when visiting all GeoStream pages on Windows Vista:
HTTP Error 500.19 - Internal Server Error
Description: The requested page cannot be accessed because the related configuration data for the page is invalid.
Module IIS Web Core
Notification BeginRequest
Handler Not yet determined
Error Code 0×80070021
Config Error This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault=”Deny”), or set explicitly by a location tag with overrideMode=”Deny” or the legacy allowOverride=”false”.
Solution:
Enable ASP.NET with this:
Control Panel -> Program and Features -> Turn Windows Features On or Off -> Internet Information Services -> World Wide Web Services -> Application Development Features -> check ASP.NET
If ASP.NET is already checked, uncheck it and then check again to reinstall it.
