At our college, we are setting up all staff machines that are "thawed" in a Staging group and then deploying the updates to the agent. However, all of our lab computers are "frozen" via DeepFreeze, and we want to exclude them from receiving updates until a specific date and time when we thaw them and need to trigger the agent updates at that time. What is the best way to make this happen? I would put all frozen machines in a staging group, but I don't see how to only trigger certain ones to update, and not all of them in the group. Thanks in advance!
