About the My Test Machines Group
One hard lesson that many administrators have learned is the importance of testing new implementations before rolling them out to critical production systems. In anticipation of this need we have created a default group for you to use for this purpose.
You can use this group just like any other. Simply add either lab machines or low priority production systems to it. You should take care to make sure that you have a representative mix of machines in the group in order to cover the production systems on your network.
For instructions on adding machines to this group, see Machine Group Pane: Middle Section.
