Message "Forbidden" when I enter commandbox: start

I am new to commandbox. Here was what I did:
Installed commandbox with success
set up local web server IIS
When I tried to enter : commonbox: start, I got “forbidden” message in my browser : 127.0.0.1
Is it permission issue or I need to do more config?

thanks

Hi Shen Wang,

Check and see if you have an index.html or index.cfm file in that folder. That might be as simple as there not being a default page to load and the server not allowing directory browsing.
