Using IIS 7.5, it is intended to use the IIS_IUSRS account. I get "401 - unauthorized access: access denied due to invalid credential error." If I add an EVERYONE account to Read, it will work. But rather, you do not have an Everyone account. Any idea why IIS_IUSRS is not working? It has read access. Anonymous access = enabled. Specific User = IUSR
As a side, in the section "Basic settings ..." for the site, the button "Test parameters" says "ok-on Authenticate", but authorization "cannot verify access to the path."
