This is caused by IIS not allowing unlisted extension to run. For more information refer to



As per the MIcrosoft KB, allowing unlisted extension to run resolve the problem.

To allow unlisted extension to run:

  1. Open File Explorer and go to %windir%\System32\inetsrv\config
  2. Create a backup copy of applicationHost.config
  3. Edit the applicationHost.config
  4. Search for <requestFiltering> section
  5. Change <fileExtension allowUnlisted="false"> to <fileExtension allowUnlisted="true">
  6. Save and restart IIS services
  7. WebAdmin should now be accessible
