Office 2007 MIME type fail.
IIS6 doens’t know what to do with Office 2007 documents until you inform it of the proper MIME types… that’s fine, understandable.
It gets interesting though if you fat finger your copy and pastes and tell it that docx == powerpoint!
Given that under the hood all these files are XML it will go ahead and start rendering all your hosted .docx files as PowerPoint presentations, slides and all. Pretty wild!
Took about two seconds for me to realize what had happened once I got my first call from a user!
