http 404 error for other php pages

[Anon]

NOW the URLS such as http://localhost/manual/new_features_1_3.html and
http://localhost/index.html.en etc.
are available on IE 5.0 to me.
But the site named "try" still doesn't work.(ie. the URL http://loaclhost/try/index.php still gets HTTP 404 ERROR, the same question occured on some other sites under the localhost. The sites are edited with Frontpage 2k

Please give me some advice to resolve it!
THANKS
Baker

(PWS is nstalled, however it's stoped when I 'm running Apache)
The path for the "try" folder is available too.
The system is WIN 98 SE(including IE 5.0) of Chinese version, also including Apache1.3.20+PHP4.06
