Install Problem

Hello: I am having trouble getting PHP to work on in the following environment o/s Win2000 Server Webserver IIS 5 PHP v.4.3.9 At first I tried to manually install and it appeared to fail. Then I tried using the Windows Installer from the PHP Website and it seems to fail. I loaded a simple test file called "hello.php" into a domain directory and tried to call it using a browser. I continue to get a 400 error Bad Request The Page Cannot be Found... The file "hello.php" is in the root directory of the domain... I have renamed the php.ini.recommend file to php.ini and moved it into C:/winnt directory Is there a better step by step installation guide out there for the above installation environment? Running php -f hello.php from the cmd prompt in the appropriate domain directory results in the file being properly displayed. Any ideas? --Bruce
