Installation? problem for php newbie

I manually installed PHP 5.0.2 and have also used the installer. In either case when opening a php page via IE 6 or Netscape 7.1 the HTML code displays but not php code. When checking the source I can see the php code. No errors are generated so I am at a loss as to why php is not functioning. I'm using Windows 2000 Server SP4 Below is the code for "test.php" which is located in H:\Inetpub\wwwroot and PHP was installed to H:\php <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> <body> <?php phpinfo(); ?> Hello World! </body> </html> Any suggestions will be very much appreciated. Thanks, Michael P.S. Sorry if this is a duplicate posting.
