Jeffrey, you're speaking French...
How do i do that? enable PHP in web service extensions...
Also, how do you turn off IIS?

I hate to sound like an idiot, but I'm having the same problem.
I'm running Windows Server 2003 on a developement machine.
Using IIS 6.0.
I think i have PHP 4.3.7 and MySQL 4 installed.
I copied the files from the HTML dir to my root; D:\Xoops and all the files are there.
I've told IIS to use index.php as the default document and when i go to my local web in a browser, i get this:
HTTP Error 404 - File or directory not found.

I can get any HTML or ASP web running on this machine, but this one's got me baffled...
