When try to open Office 2007 documents (.pptx, .docx, .xlsx) from the intranet, my computer tries to open them as a .zip file rather than the Office document itself .

Any ideas why?

Does this only happen when using documents off the intranet? When you open a natively stored pptx or docx file does the same thing happen? –  Joe Taylor Feb 18 '10 at 16:43

Sounds like someone has messed with your extensions to treat them as zip files. I'd try an Office "repair" from control panel add/remove programs to change them back. Obviously this is not normal.
