County has ISA2000 that all schools authenticate to to get internet access.

Problem is that streaming media does not work through it.

We have installed ISA Server firewall client on a machine and have setup protocols to allow realmedia streaming through the network, but its not working.

If I hover over the firewall client icon on my client machine it says "ISA server could not be detected"

and real media player will not connect to outside world.

Any advice would be appreciated
