Having been down this road, I think "inaccessable" needs emphasis.  Many
other 400 series error codes don't deny the existence of the URL just that
you haven't the proper access credentials.  A browser may well be able to
access the URL because either (a) the user knows the password or (b) the
browser knows the password (NTLM authentication).  Of course, the browser
may know about many other important bits such as proxies.

And don't bother using "HEAD" -- you'll get the wrong answer too many
times.  Just use GET.
