ASR Problem

Hi, I'm using ASR to learn how to multicast an image and I'm stuck at a problem. I have the image that passes scanning, and I can start the stream on my server (Mac OS X Server 10.4). The client requests the image and then goes and erases the drive like it is supposed to, but as soon as it starts to restore it throws an error.

asr: failed to read the stream: can't assign requested address

My problem is, I don't know what this means. I know the client has already communicated with the server at this point, because the server detected the request and started sending the data over the network. Can anyone clue me in on what might be the problem?
