All of our network traffic is routed via our MS ISA 2006 server.
We've got an issue with a few websites that use flash content, the main one being youtube (staff access only)
When flash content is accessed on the site it'll either just sit there loading or in the case of youtube tell the user that their flash player needs updating.... which it doesn't.
the flash content works fine if ISA is bypassed
any assistance would be much appreciated
