I'm new to working with MS Server 2008 & IIS 7. I need to install PHP on this server and am not sure whether I should go the manual route as detailed on the official PHP site, or use Microsoft's Web Platform. I'm initially going to be installing a CMS like Drupal or perhaps MODx, but may need to implement other PHP-based web application on this same machine. Is there a difference in these two installation methods that could cause me problems down the road? Has anyone had bad experiences with Web Platform?
PS-I'm pretty sure this server instance will end up being my production/live site so I want to set it up right from the beginning. I work at a school which is meager with it IT resources and have been told they won't set me up with another "virtualized" server installation for testing/development.
