It seems that no matter what i try, any media player using Microsoft Silverlight is blocked from viewing on the Internet by default by our WSA. Any other media player that I have seen works within a user access policy that I have setup. I am trying to view a Sharepoint 2010 presentation on microsoft's site and it is not working. I have the entire .microsoft.com domain added to the proxy bypass list and it still will not play. I have to add the IP of the users pc to the proxy bypass list to get it to work. This is not a secure nor feasible method for viewing say a benefits presentation or software presentation for example. Please help. Any suggestions to remediate this would be appreciated. Thanks.
