I have been troubleshooting this problem for months now, and I don't seem to be very close to solving the issue. I have a particular building that I can use windows media player 11, or any version to view streaming videos. This is the only building out of 4 that can use windows media player 11, or any version. I have. Can someone help me out with this? All computers are configured the same, the only differences are each building has it's own OU, so I'm thinking this has to have something to do with group policy. I'm just having a hard time figuring out what is different between each OU's group policies.
