Blast from the past: PHP install not working on old Netscape Enterprise Server 3.62

We're stuck using our existing Netscape 3.62 servers for a little while longer and need to install PHP for some new Web pages that are coming soon. I followed the directions for installing PHP under Windows NT at <http://benoit.noss.free.fr/php/install-php.html> and at <http://www.wrox.com/consumer/errata/2963/php_new.htm>, but pulling up a test.php file in a browser doesn't work-- I get a 404 error. The Web server log shows: [23/Jan/2002:09:30:23] warning ( 194): send-cgi:failed to get associated file for (/htdocs/the_site/test.php) Error 2 [23/Jan/2002:09:30:23] failure ( 194): for host 10.1.252.103 trying to GET /webpb/test.php, shellcgi-send reports: can't find file association of /htdocs/the_site/test.php for execution (The file association under NT works. I can confirm this using a test.php file and a test.bat file as described under the benoit.free.fr instructions. That association tests successfully. I'm not sure what assocation is failing according to the error log.) Does anything jump out at you as being an obvious problem? Thanks for any help you can offer!
