Error with IIS

Hello everybody ! I want to run PHP 4.3.2 on my IIS 5 on Win2000 Server. When i want to open an .php file I always receive the error message "The specified module can't be found". I assume it is an beginners error I made, I took all steps explained on MS Technet http://www.microsoft.com/technet/treeview/default.asp?url=/technet/prodtechn ol/iis/iis5/deploy/depovg/miglamp.asp but it doesn't seem to be enough. I also saw in the ISAPI-Filters (in the properties of the domain where I want to add the PHP support) the phpisapi4.dll is added but has the Status "Not loaded" - maybe this helps you. As I found this bug in your support page where it is told to contact you I now do so. Thank you for your help, Best regards, Klaus Reichl
