here I got this from the beginning php4 errota on the wrox web site dealing with IIS
Getting PHP4 up and running on IIS
Comment from Allan J Horwitz (DEVONS02@aol.com)
I know many of us have had
problems getting it to work so here's something that I tried and it now works
like a champ. In your book Beginning PHP4, there is a great example of how
to install php4 on IIS. One detail, however, is left out (I believe). They
forget to mention that when making up a name for your ISAPI filter, that you
should NOT use the same name as the directory that you store PHP in. What I did (just playing around on a lark) was to name my ISAPI filter PHP4 since I don't have a PHP4 directory anywhere on my system. When I did that,
everything worked without a hitch. So my pearl of wisdom is that you should
give your ISAPI filter a name like PHP405 (or whatever, as long as it is not one of your directories) and everything should work fine. This should save a lot of people the headache of getting Error 403 (or is it 404?) saying it can't find the program.
Remember I did not type this it is from www.wrox.com under P2P beginning PHP4 errota. 🙂
