HTTP Error 500.19 – Internal Server Error – 0x80070021 (IIS 8.5)
I started getting below error in a fresh box where I have got windows 8.1 and Visual Studio 2013,
HTTP Error 500.19 – Internal Server Error
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 | 0x80070021 |
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”. |
To resolve the above I just enabled the Application Development Features under Word Wide Service as shown below
I hope this might help you.
