Has anyone come across “Anonymous ACLs gone bad”. I set some service ACLs to “Anonymous”. (I need anyone to access these services without authenticating to IS).

I tried setting/resetting the ACLs, and restarting the server to get it to reload the Anonymous ACLs - to no avail.
This problem is limited to one machine: One funny thing I’ve noticed on that machine is I don’t get the “Access Denied” message anymore when I hit “cancel” on the “Basic Authentication” dialog. Instead I get a HTTP 401 response and a blank page.
In constrast, on the machines without this problem, my browser get the following HTML when I hit “cancel”:
