I want to install a Windows 7 image on 40-something computers without touching 'em

I have a WDS server, an image captured, and an answer file setup. I go to create a multicast transmission out of the image, but I can't see it on my client computer.

I think it may be because my router doesn't support PIM (it's an IPCop firewall) but I'm not sure it would need to if I'm just multicasting to client computers within the network that the router.

So my question: if I want to do this, will I need to have a router/firewall that supports multicasting in order to multicast to client computers on my internal network?


Yes, all parts of the network between the server and the client will need to support multicast. The WDS server needs to be configured, DHCP needs to support multicast addresses and the router/switch needs to understand it.
