Removing a computer from a computer group removes the computer from the group, but does not delete the computer from the Configuration Database.
To remove computers from a computer group
In the Scope pane, expand Computers.
Click the Computer Group to display the computers in the Result pane.
Right-click the Computer you want to remove and choose Remove from Group. The computer is removed from the computer group, but remains integrated in Symantec LiveState Delivery.
