I have a lab environment setup specifically for imaging laptops via WDS. I have a stand alone Windows 2012 server connected directly to an 8-Port Cisco SG-220 8 Port switch. Nothing else is connected to this server and it is not being used for anything else. The server is running DHCP and WDS. I can boot laptops via PXE and connect to the WDS server to deploy the images through standard WDS imaging. However, I have not been able to get Multicasting to work. I have never used Multicasting before and have read through the documentation but must be missing something. This is what I've done:
1. In the WDS server I right click on my deployment image and select 'create multicast image' then go through the prompts to create an auto-cast image.
2. The Multicast image is created and shown as 'waiting' on the WDS server.
3. The Cisco router is brand new out of the box, the only configuration I did was to enable IGMP snooping. I did not make any other changes to the setup of the switch.
4. I boot a target machine via PXE using the same Boot Image that I always use. It loads to the screen where I can select the image I want to deploy but it never shows the multicast image as an option. I only see the regular image I had previously been using.
I'm not sure what else I'm missing in order to get the target machine to connect and image using the multicast image.
Here are a few screen shots of what I have setup:

Here is the Cisco Router configuration:
Here is the NIC card configuration on the server:
This is the target laptop booted via PXE but it never shows the multicast image as an option.
