A couple weeks ago I sent out a Policy Supported Push to about 13,000 PCs. These 13,000 PCs are found on about 1500+ different subnets. The push was about 150MB so I used Target Multicast. The delivery method was set to 40 devices at a time, Targeted Multicast, 25%WAN and 75% Local. This job has been running for literally a couple weeks. I have been monitoring the results and I have developed a couple of questions from this.
1. In the delivery methods used for this push, I noticed under Network Usage > Multicast limits the Maximum number of multicast domain representatives working simultaneously is set to 5. Does this mean that even though 40 devices can recieve that push at a time that only 5 Multicast Reps are actually allowed to be pulling down the files?
2. There are about 5000 devices in the Active state in the Scheduled task that have a Status of "Multicast failed, could not find a multicast domain representative". I have not been able to find any documentation of what this error means specifically (though the error itself sheds a little light) and what will happen with these machines. Will they wait their turn to pull down the job from the core directly since a Multicast rep was not found or will they just give up and eventually fail?
