IIS everything is download only

[jeff.sadowski]

Some of my developers want in "Default Web Site Properties"->"Home Directory" under "Execute permissions:" for it to be "Scripts only" but for some unknown reason the site hiccups once a day and enters the download only mode so that when you go to a page it asks if you want to download it even for the index.htm pages. To set the site right again I set "Execute permissions:" to "scripts and executables" and hit it with a web browser then I set it back. If I leave it as "scripts and executables" some of my download links no longer work. I seem to recall having this problem a long while back but since I hardly ever deal with IIS I never bothered trying to find a solution or even the cause. Can someone point me toward the documentation on how to fix this issue? I'll look through the logs and see if I can find an event that might explain it too but it is weird that setting it one way and setting it back fixes it temporarily.

Does the issue occur every day at the same time or is it random? Is there anything specific happening when this occurs?

Rebooting fixed it although I have no idea why it started.

Event logs are your friend.
