Hi, I tried disabling the anonymous access on both a virtual directory and a new website (port 81) but I still get the error. The only authentication is integrated auth. I started using the wizard so the rest is default. Of course my default webpage is set cachemgr.cgi and not index.html or something like that. Maybe you changed some other things while testing? Kind regards, Jeroen.
