WDS and Multicasting : the session is starting too soon

[cyr0n_k0r]

I have already setup and deployed our image (XP) through WDS for some time now. Everything has been ironed out and it works great. Now I am trying to finish the final stage which is getting multicasting to work.

I setup a new multicast session however my problem is that I want to use Scheduled-Cast with the threshold argument. I want to wait until 50 computers are connected before the session starts.

Here is my problem, after I get only a few clients connected, 2 or 3, the first couple just start imaging. They don't wait. They will sit there for about 30-45 seconds with "waiting for server to initiate session" or something like that and just start the image process.

While they are waiting they show up in my multicast session on the WDS server and I can see their MAC address and client ID and all that, but as soon as they start imaging they disappear from my multicast.

I've tried searching but can't seem to find people that are having this same problem.
