PHP on IIS4 problem

Hello, I am newbie to PHP and have been trying to install PHP on my local W2k IIS4 until I get the chance to setup a Linux box. I used the window binary from php.net with installer PHP 4.3.0 installer (CGI) The installation ran smoothly. and I checked for permissions although I am not on NTFS . The IIS renders php files as regular html without executing the code enclosed within the <?php ?> tags I also ran c:\php\php.exe -i and it rendered indeed the proper html document without any errors. Under the IIS Manager >> properties >>WWWService>>Home Directory>>App Mappings .php is already associated with c:\php\php.exe with all verbs option and script checked It just won't work !! any help is greatly appreciated thanks in advance PC
