Re: Vista behind ISA proxy
The truth is that I haven't figured this out yet b/c I haven't had a customer
onsite with a Vista laptop since I posted this back in Sept. The issue for us
is strictly with non domain member Vista machines that refuse to see that
they are behind an ISA proxy. Until there is a workable resolution that
allows this OS out through ISA using proxy auth my answer will simply be that
we don't support outbound guest connections through the proxy and they'll
have to relocate to an area that I have setup using a different outbound
method. It's restrictive but necessary.
I can't believe that getting a vendor's product to work with another of
their own products is so difficult. Either I'm just missing something or
someone @ MS dropped the ball.
Good luck and please post back here if you solve this.
