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.
