1 In the Symantec Endpoint Protection Manager console, click Clients.

2 On the Clients page, under View Clients, select the group for which you want to disable or enable inheritance. You can select any group other than the group that is associated with the Temporary group.

3 In the group name pane, on the Policies tab, do one of the following tasks: To disable inheritance, uncheck Inherit policies and settings from parent group "group name". To enable inheritance, check Inherit policies and settings from parent group "group name", and then click Yes when asked to proceed.
 

thanks Guys..!
