[isalist] Re: ISA 2004 web proxy authentication

This is operating by design.
Computers aren't authorized; users are.
Most Web applications will try anonymous requests, get rejected by the proxy, 
then negotiate a mutually acceptable auth mechanism.

Subject: [isalist] ISA 2004 web proxy authentication

I seem to have an ongoing problem with the web proxy authentication.  I get 
frequent denied due to anonymous proxy entries from the same computer that also 
has non-anonymous entries.  I am not sure but it may just be SSL tunnel through 
port 443 that it happens to, that is the only instance I could get to occur and 
fail just recently.  I basically get the 12209 failure due to authorization 
required, but I am on a computer that is otherwise authorized.  All users must 
authenticate (or whatever it says exactly) is NOT checked off.  If I uncheck 
"use a proxy server" in internet explorer, it seems to work, but I don't think 
I should have to uncheck that.  Why does ISA not recognize the authorization 
some times?

Sorry for my lack of a direct question and my ISA-LESS knowledge, which I ain't 
to proud to admit to.

Thanks.
