Hello,
You can see some of these tutorials:
http://www.devarticles.com/art/1/202/2
and
You may not choose iis when you run install of PHP, or iis is not working properly, to test your iis
type this ASP code in a text editor and save the file as anyname.asp in any web shared folder to test
<% for i = 1 to 10
response.write("Hello "&i)
next
%>
and open the file from the broswer as usuall?
and see if you get an out put or not.
Do you have Zone Alarm fire wall?, in some cases it makes some problems with iis in winXP
Recomended for you to use Apache Server, you can get PHP Triad, it's a complete free package, (PHP, MySql, Apache)
