Hi all

Platform: window2000  
PHP version: 5.2.5

I got a problem … php can’t load MySQL module  
Originally, PHP and MySQL were working fine  
but after I have updated to Service Pack 4, all ASP and PHP not working  
And there’s an error came up in Event Viewer  
“[COLOR=red]The HTTP Filter DLL C:\Program Files\PHP\php5isapi.dll failed to load.”[/COLOR]  
Then I google the solution, fixed this problem, ASP and PHP load correctly now  
However, PHP doesn’t load the MySQL module …

in the php.ini (that is located at C:\winnt)

- the line of extension=php\_mysql.dll has been uncommented
- the extension\_dir is addressing correctly
- MySQL is working fine

Is there any other reason might cause the MySQL module no load ?  
the php.ini has been attached with this post

Thanks
