Any one know a step by step explanation on how to fix this , I tried
everything and searched everywhere.
The server is configured to use pass-through authentication with a built-in
account to access the specified physical path. However, IIS Manager cannot
verify whether the built-in account has access. Make sure that the
application pool identity has Read access to the physical path. If this
server is joined to a domain, and the application pool identity is
NetworkService or LocalSystem, verify that <domain>\<computer_name>$ has Read
access to the physical path. Then test these settings again.

IUSR, IIS, gave permission to everything and everypossible user and still i
get this.
