Step 4: If Web.Config is not present, copy one of the samples provided in the /webconfigs/ folder into the root of the web application and rename to web.config.

Question: Is this referring to the web.config inside of "YAF" folder or my root or host folder?

Step 5: Also you'll need to add the element to the web.config to point to the correct URL. Example: If you have install the forum in the directory "http://www.yoursite.com/forum/yaf/" you will need to add /forum/yaf/ to web.config.

Question: Is this referring to my root or host web.config file?

And finally, when I navigate to "http://localhost/Test/yaf/" got the following errors:

HTTP Error 403.14 - Forbidden

The Web server is configured to not list the contents of this directory.

Any help is much appreciated.
