Abit ironic that ISA is blocking Microsoft Silverlight! It is stopping content being shown on sites such as ITV Player.
This is a post with a similar issue - [isapros] Re: Silverlight through ISA 2006 - isapros - FreeLists
Does anyone know how to fix it please?
We are running ISA 2006
Edit: this is another site we get the problem with: http://www.microsoft.com/emea/spotlight
