I just did a fresh install of Zenworks 11 SP2 on a brand new server. We have been using Zenworks 10.3.x, but due to some Windows problems on the server, decided to start all over. All computers have ZCM Agent for 10.3.4

My question is, I know how to unregister a device from a Zenworks zone, but I have 100 computers. How would I unregister all 100 devices from the zone at once? I don't want to have to goto each machine and run command line manually. Please help.
