After Windows network polling is complete, the found devices are placed into subgroups of the Unassigned devices administration group. This administration group can be found at DISCOVERY & DEPLOYMENT → DISCOVERY → WINDOWS DOMAINS. The WINDOWS DOMAINS folder is the parent group. It contains child groups named after the corresponding domains and workgroups that have been found during the poll. The parent group may also contain the administration group of mobile devices. You can configure the retention rules of the unassigned devices for the parent group and for each of the child groups. The retention rules do not depend on the device discovery settings and work even if the device discovery is disabled.
To configure retention rules for unassigned devices:
The Windows domain properties window opens.
The child group properties window opens.
Your changes are saved and applied.
