UdpClient.JoinMulticastGroup fails under Vista

Can anyone explain why an attempt to join a multicast group at address
224.0.0.1 using UdpClient.JoinMulticastGroup() fails under Vista with a
socket exception "A socket operation was attempted to an unreachable host".

Running under elevated privileges makes no difference.

All other addresses in the multicast range work fine.

Performing a tracert command results in a transmit error: 1232.

Regards

Steve
 
More information if anyone else is experiencing this problem.

It appears that joining the multicast group at 224.0.0.1 will fail if your
machine has either Wireless or Bluetooth network adapters enabled. Disable
the adapters and it appears to work.
