OK, I uninstalled and resinstalled in the order you suggested, and I did get a slightly different result. Now, instead of nothing happening, I get a page not found error. This is odd because I can navigate right to that directory and see the file there. Everything else works just fine on the server, as this is an existing production server, but something is clearly wrong with how I'm setting up PHP.
I followed the steps here:
http://learn.iis.net/page.aspx/247/using-fastcgi-to-host-php-applications-on-iis-60
and used the scripting option. The first time I went through this, it all behaved as expected, and all the settings appeared correct. After reinstalling and testing my phpinfo() script (test.php, mentioned before), and getting the error, I tried running the script again. It tells me that PHP is already added.
I don't set up windows servers, so this is totally new to me. Any other ideas?
Thanks,
Caleb
