There are multiple log files, but I would expect nothing to be in the log
because that's IIS rejecting the request, not the SP.

A 401 from IIS on the handler location like that is not coming from the
SP, as there is no authorization from within the SP on those requests.
Therefore, your IIS server is the issue, and it has to be fixed to correct
the problem. There is some kind of permission issue that aparently is
causing the problem. There's not really anything else to say about it,
it's an IIS question. There are lots of security settings in IIS for
controlling access by means of Windows security and such, and something
like that is probably involved.

The handler locations are virtual, so there's no file to fix or directory
to check, it's a server-space setting of some kind involving that URL tree.
