Installation problems

I have been attempting to install php4.3.3 on a Win2k SP3 machine running IIS5. I have gone thru every installation/configuration guide I can find. I still cannot view phpinfo. I created a test.php with <? phpinfo(); ?> in it. All I get is "The page cannot be displayed. I have tried putting php.ini in the WINNT folder & the WINNT/System32 folder. I have made extension_dir = c:/php/extensions doc_root = "c:/Inetpub/wwwroot" or doc_root = "c:/Inetpub" I have edited the registry per instructions from php.net. No luck. Very Frustrated! Hope someone can help this useless person! Yeah, I'm at the end of my ROPE! Thanks in advance.
