We have a strange problem with our ISA 2006 single nic on Windows 2003. It has only one function and that is a proxy server, I know why use ISA at all then. But we are in a migration so it will be a backend firewall in due time :-)
The problem: I've got an access rule that allows all traffic to all networks (proxy style), with the condition All Authenticated Users.
Everything is fine, users get authenticated, but when we access Streaming media files an authentication popup appears.
And we don't want that, when i monitor i see de anonymous connection being denied, but i never see a authenticated session as I would aspect.
When changing the condition to ALL USERS, all is fine. But that's not ok, then i don't need ISA at all.
Hope that somebody can put me in the right direction. Regards,
