Changing MIME Type at the global (Websites) level requires restarting IIS to
take effect. If it was per-website then it would have taken effect
immediately.

The default MIME Type in IIS for .exe is application/octet-stream .

Since it is a static file download, it is possible that you are seeing a
response from the kernel mode cache of your earlier requests. I recommend:
NET STOP HTTP /Y & NET START W3SVC

to clear everything out and start again. I also recommend using different
machines for the server/browser.

OK.
First, thanks for the reply!
I have Ethereal installed so I used it instead of NetMon.
I removed the MIME type for EXE. Did not perform an IISReset.Started
Ethereal. Clicked the link and still got the same error message.
The file was downloaded (I can see HTTP Continuation packets). When I looked
at the download type it was still set to the MIME type that I just removed
(application/x-msdownload).
Went back to IIS Manager and started at the top of the Web Site Hierarchy
looking for a MIME definition for EXE. There was none at the server level,
none at the Default Web Site Level, none at the Virtual directory level.
Performed an IISReset. Started Ethereal. Clicked the executable link and got
the same error message. Looked in the capture file and the file was
downloaded again, but the MIME type was still set to
application/x-msdownload.
OK. I'll bite. Where is this MIME definition coming from if it is not
defined in IIS Manager? Do I have to perform a hard reboot?
