Okay, I have ISA Server 2000 running as my proxy firewall in a school environment. What I need to do is set up a rule so that a group of teachers can play streaming media on their PCs, but no one else can. I have tried to set up a protocol rule thatonly applies to their group, and though that worked, it blocked everyone else's access to the internet. Oops. The other problem is this: I have quicktime and Realplayer coming in over HTTP instead of the RTSP or other streaming media protocols. WillI have to disable the streams from coming in through HTTP? Is there a way that I can set access to the HTTP ports that the streams come in on? What if I was to just block the certian web sites that the streams come in on? Does any of this make sense? :-)
Thanks for the help...

I assume you're running Active Directory.

You'll need to install the ISA firewall client on your desktops. Add your teachers to a group, and then setup a policy that allows only that group to play streaming media.

Here's a good article on howto set up ISA for streaming media.

BTW, I would recommend not allowing streaming media to come over HTTP. I'm not an expert on Real Player, but I think you can configure it to work in a different port (the default is 554). Windows Media player uses 1755. When you don't use HTTP, you cut out alot of the HTTP overhead and improve throughput.

Thanks for the help here... I'm in the process of getting the group's policy to work, but it looks like it should go through. And I also re-worked Real and QT to not use HTTP... works like a champ. Thanks again for the help!
