      Discovery Center web interface displaying 500.19 error after successful install

      Sometimes after installing Discovery Center, you may receive a 500.19 error in the web interface.

      This is caused by a restrictive configuration of the parent IIS settings in the applicationHost.config which prevents the site from configuring the settings required for the operation of the web interface.

      Resolution

      Run the following commands in a command window on the system where Discovery Center has been installed:

      1. C:
      2. cd \windows\system32\inetsrv
      3. appcmd unlock config -section:system.webServer/handlers
      4. appcmd unlock config -section:system.webServer/modules
      5. Use the IIS Manager to restart IIS and the Application Pool for the Active Navigation site
