I'm trying to install Drupal on IIS6 and think I have some file permissions issues. I've made it past the database screen on the installer, but am getting this php error:
PHP Warning: fopen(./sites/default/settings.php) [function.fopen]: failed to open stream: Permission denied in C:\Inetpub\wwwroot\includes\install.inc
It appears the Internet Guest Account as Read and Execute permissions on everything. What else could I look for?
