Managing client systems System management allows you to import system information into McAfee ePO. This is useful in the process of installing MNE and viewing the list of FileVault or BitLocker users. Client systems are managed by McAfee ePO through a combination of product policies. You can identify systems that require the same policy settings, and place them in a system group. This grouping allows you to update the policy settings to all systems in that group at the same time. Add a system to an existing group You can import systems from your neighborhood network to groups through McAfee ePO. You can also import a network domain or Active Directory container. Move systems between groups You can move systems from one group to another in the System Tree. You can also move systems from any page that displays a table of systems, including the results of a query. System actions Use system actions to perform actions like recovering MNE and importing the recovery key. Maintenance mode on BitLocker systems This feature allows you to temporarily disable pre-boot authentication on BitLocker systems, in order to roll out Windows or software updates that may require a system reboot. To use this feature, the maintenancemode-x.x.x.x.exe file must be copied to the system, and executed with command-line parameters within the roll out scripts.
