A web site that used to work now doesn't. It seems to have
been a spontaneous event, but I may have inadvertently
changed a setting. I've narrowed it down to the fact that
in IIS->myWebsite->Properties->Directory Security->Enable
Anonymous Access the "anonymous access" option no longer
works. The web browser is asking for authentication.
According to the docs, the web server should try to use
built-in guest account IUSER_USEBESTMAIL, and only after
failing that should ask for authentication --- UNLESS there
are file permissions in the way.
Is there a way to clear all the permissions so as to start
fresh and put them only where they are needed?
Can you suggest another approach?
