IIS 5.1, PHP 4.3.9, Getting Error 400

Hi,

Despite reading all the other messages people have posted with similar problems, and having tried damn near every suggestion out there, I still cannot get PHP scripts to execute.

I installed an configured IIS 5.1, PHP 4.3.9 on WinXP Pro SP2. Despite doing all of these steps, I'm still getting HTTP error 400:

- I have installed PHP to C:\PHP\
- PHP.INI file is in C:\PHP\, not C:\Windows.
- php4ts.dll is in the PHP directory as well as System32.
- Application Mappings for .php set to C:\PHP\pxp.exe
- IUSR_ Account given read/execute permissions to C:\PHP as well as C:\Inetpub\wwwroot

I'm trying to use CGI mode. I can't get ISAPI filters to load properly. (Nothing works)

I've googled this problem to death, followed instructions to a "T" on the PHP site, as well as some third party instructions, and I'm still at a loss.

Help?

I found the prblem, the INI file got overwritten and cig force redirect was commented out and set to '1', so I set it to '0' and it seems to work now.

But i have a new question -- I use _SERVER['DOCUMENT_ROOT'] in a lot of my programs I build for the web (mostly Apache Servers), and there is no _SERVER['DOCUMENT_ROOT'] variable. I tried setting it up in PHP.INI, but it didn't show up.

I setup a few virutal directories in IIS to point to directories on other drives, where I store the website files (I prefer not to use C. Is there a way for me to use _SERVER['DOCUMENT_ROOT'], and have aliases show up properly? Ex:

F:\Websites\Foo would be set up as http://localhost/foo/

I would like to get _SERVER['DOCUMENT_ROOT'] on that site to point to f:\Websites\Foo, to minimize the amount of re-programming I would have to do when uploading the PHP files to an Apache envirenment where the _SERVER['DOCUMENT_ROOT'] is /home/sites/foo.com/htdocs/ or whatever.

ANy suggestions?
