ISA 2006 block media player
Posted on 2011-03-25
I just built an ISA 2006 server running W2K3 with the following settings. The ISA server is just used for web proxy.
Enable HTTP with port 80
Integrated and Basic Authentication
Requires all users to authenticate
When a user outside our network firewall trys to connect to a webcast that is using Windows Media Player, the player show all the correct images but does not start. When I try the webcast internally, it works fine.
My old ISA 2004 server works fine for users outside our network firewall.
The only difference between the 2004 and 2006 is that the 2004 does NOT require users to authenticate. Could this be the issue?
