Problem installing PHP4 with ISAPI on IIS 5.0

Hello, I got the bin ary distribution on the php site, and i try to install php4 using the ISAPI DLL called php4isapi.dll, but i got a problem, IIS 5 don't want to load the dll ! Here is what i do : - I unzip the distribution in the c:\php4 directory - I rename the php-dist.ini in php.ini and put it in the c:\winnt directory - I edit the php.ini and modify these lines : - doc_root = d:\Sites ; wich is the root of directories that host the virtuals servers (many domains) - extension_dir = c:\php4\extensions - and i uncomment some modules - After that i select one of the site i host and i click on the property menu - Then i click on the ISAPI filter tab and add an entry specifying "PHP" for the name, and the path to the php4isapi.dll - After that i click on the directory tab, click on the config button and add an entry for the .php extension that point to the php4isapi.dll - Then i stop the IIS 5 services, and once stopped i run the services on After that PHP don't work so much, i got a strange mesasge in the event viewer that don't tell me anything ... So if somebody have an idea .... Many thanks for responses. Alain from France.
