If you’re new to IIS 7 (you probably are) you might receive this nice little gem when you first start working with it:

HTTP Error 500.19 – Internal Server Error
Description: The requested page cannot be accessed because the related configuration data for the page is invalid.

IIS 7 implements “Configuration Locking“. This is to help with IIS administration. The IIS Administrator can lock down Configuration Sections, Section Elements and Attributes at the IIS level. This allows the administrator to have a more granular level of control on the system. Read this link to see more about it.

Important Note: In order make these changes, you must be an administrator on the machine where the config file resides. If its on your local machine, you must be an administrator on your machine.

Since I’m on my own development machine, and since this is a development machine, I have decided to change the global setting (the config section itselft). To fix this error I had to go to the applicaitonHost.config file and set the overrideModeDefault to “Allow”.

Here’s how:

Open the applicationHost.config file, located here: %windir%\system32\inetsrv\config\applicationHost.config

In my instance, I need to edit the “handlers” section.
