[users@httpd] Appache localhost server denied access

[Brian Fisher]

I have set up a local server using Wampserver but I can’t access it from the 
same computer with http://localhost/pnpTest.pnp or http://127.0.0.1/pnpTest.pnp 
in IE8 browser.
My file pnpTest.pnp is in folder C:\wamp\
Neither can I access http://127.0.0.1/pnpmyadmin/ as it asks for a username & 
password.
