any time you edit your httpd.conf file you need to restart apache for the new settings to take effect. and since you set apache to not listen to a default httpd port (you changed it to 85), you will need to access localhost like this
[
localhost]
if you do not want to have to use the :85 part, then chnage the port apache listens too to 81 or 8080.
also make sure apache is running. also make user you server is in the correct mode..
