doesent work : WINNT with PHP4+Apache 1.3.12

Hi, OS: WINNT 4.0 SP6 The Apache 1.3.12 is running fine. Then I installed PHP4 in c:\php4 . I did some modifications in php.ini (it resides in C:\WINNT): doc_root=d:\wwwroot\cgi-bin (that's my localhost bin_dir directory) extension_dir=c:\php4 (that's where php.exe resides) I also did some modifications in httpd.conf from Apache: ScriptAlias /cgi-bin/ "d:/wwwroot/cgi-bin/" AddType application/x-httpd-php .php3 Action application/x-httpd-php "C:/php4/php.exe" Every time I try to call a php page in my browser (like http://localhost/test.php3) I get the error: "The page cannot be found" What's wrong ?? I'm totally confused ! Thanks a lot !
