HTTP Error 403.14 - Forbidden

Question

I received the above error and it was suggested that I tried the below solution.

 

Go to the IIS Express install directory.

1. Run appcmd set config /section:system.webServer/directoryBrowse /enabled:true to enable directory browsing at the server level.
2. Run appcmd set config ["SITE_NAME"] /section:system.webServer
3. directoryBrowse /enabled:true to enable directory browsing at the site level.

I tried the following after research on the internet but the below solution is still giving me http error 403.14.

<system.webServer> 
<directoryBrowse enabled="true" /> </system.webServer>

I hope someone can advise me how to run appcmd

 

Tks.
