I am trying to install Php on Vista (IIS 7). The installation and configuration seems to be fine. Pretty much followed everything mentioned in http://blogs.iis.net/bills/archive/2006/09/19/How-to-install-PHP-on-IIS7-_2800_RC1_2900_.aspx I can even bring up a test.php which is basically and can also connect to mysql db through code. But when I try to bring up some other php page like drupal's index page or phpmyadmin index page, it brings up a Php access violation message. Any clue whats happening? Also is there some tracing/diagnositic tool for php to trace whats happenign on the webserver.
