I have group policy set for users to acquire automatic updates on their machines and to install at 3AM. Just like the default setting on standalone machine. What I've noticed though is the pc's are installing some but not all the available updates. I'm trying to figure out why the machines are not downloading and installing all critical updates automatically. Is this because some updates require the user to be logged with administrator priviledge? I have a few people that have admin priviledge on their pc, but most have user priviledge.
