If you choose "Save", does the PPT download properly?
FYI: by definition, IIS is not responsible for displaying any Powerpoint
presentation, regardless of authentication. What is happening behind the
scenes when you click on that file is this:
1. Client (like the IE browser) requests the URL (i.e.
intranet.company.com/just4fun/photos/LibraryCentral/takeyourdaughtertowork.p
pt ) from IIS
2. After authentication and authorization takes place, IIS can be configured
to either send the file as a download, or execute the file on the server.
In your case, IIS is configured to send the file as a download. If IIS
tried to execute the file on the server, you likely will not "see" anything
since Office documents are not web resources. Office documents work when
downloaded and viewed locally on your machine.
3. Client pops up the dialog box prior to receiving the file as a download
and asks you if it should open or save it AFTER it has downloaded onto your
machine. If you choose Save, it just downloads it to the folder that you
choose. If you choose Open, it first downloads the file to a temp folder
and then opens it.
Therefore, if the server does send the file to the client, the problem is
not with IIS. The client is the one responsible for determining save vs
open.
Thus, my questions are:
1. If you hit "Save", does the PPT file download properly? If it doesn't
even download, it obviously won't open, either.
2. If "Save" works, then can you first uncheck the "Show Friendly HTTP
Errors" option in IE (go to the Tools->Internet Options menu and select the
"Advanced" tab) and then choose "Open" again and report what is returned?

Hello -- We have an NT4.0 IIS server that hosts our companies Intranet. A weird thing has been happening. When we "Allow Annonymous Access" we can get to a page that has a Powerpoint Presentation on it. intranet.company.com/just4fun/photos/LibraryCentral/takeyourdaughtertowork.p pt When we Allow Anonymous, we get a Dialog Box asking us if we want to OPEN or SAVE the file... I can click Open, and it opened in my IE browser. However, when we set it to Basic Authentication, we still get the Dialog box asking to Open or Save but when we press Open, we get a Page Cannot Be Displayed. Any ideas why this is happening?! Thanks so much! -Blake Ringholz
