Bad form to answer my own question, but for the sake of the archive, here goes... Apparently IE doesn't like "no-cache" in a cache-control header. Changing that to max-age=0 solved the problem. Bad: header Set Cache-Control: "no-cache" Good: header Set Cache-Control: "max-age=0" FireFox, Opera, etc all do fine with either config. -Tony > -----Original Message----- > From: Tony Rice (trice) > Sent: Thursday, May 08, 2008 4:41 PM > To: users@xxxxxxxxxxxxxxxx > Subject: Errors when accessing PowerPoint and > word files, IE but not FireFox > > When accessing Microsoft PowerPoint or word files on my > webserver, I'm seeing errors accessing the file via IE > (version 6 and 7) but problems when using FireFox.
