I've set up a Multicast imaging bundle with an image and i've assigned it to a hardware rule so that any computer within a range of addresses automatically starts up PXE and joins the Multicasting session. All the PC's join the session but then all just sit there with "Waiting for Master to start the Session". Am I doing something wrong? We use to do this with Zen 6.5 and it worked great but doesn't work with ZCM 11. Any thoughts?
