I am having trouble with multicasting. I have a 4 windows 2003 SP2 servers all with ZCM 10.0.3 at different locations. I have created a multicast image bundle with my image at one of my locations. I then created a "rule" on my primary server that looks for the bios SN. I have tried on different dell machines as well as non dell machines. They boot to pxe and get all of thier IP stuff but then always exit with no work to do. Any help would be much appreciated.
