This was probably answered somewhere, but I'm an idjit

I hope I am clear and concise, but I am a total noob at all this IIS DNS, PHP, blah blah blah. I am running Windows 2003 with Apache Tomcat 5.5 and PHP5.2.5. I have a website which is almost entirely comprised of .php pages. I can view the xml, html pages, but not the .php. They always come back as "The page could not be found." I want nothing more than to be able to see my webpages, but am not certain I am putting stuff where it goes. I tried adding
Addtype application/x-httpd-php .php .html in both places it has "AddType"
AddHandler php-script .php .html
Not sure what else to do here. Any suggestions would be greatly appreciated.

A 404 error indicates that the file does not exist and is independent of the PHP configuration. A PHP error related to your Apache configuration would result in either the page being displayed as text or sent to the browser as a download.

You mention IIS. Is that also running? You could have port conflicts if it is, so I would recommend picking either IIS or Apache unless you fully understand how to get them to work together.

Did you check your error log?
