Use your NT domains as a source for populating your System Tree.
When you synchronize a group to an NT domain, all systems from the domain are put in the group as a flat list. You can manage these systems in the single group, or you can create subgroups for more granular organizational needs. Use a method, like automatic sorting, to populate these subgroups automatically.
If you move systems to other groups or subgroups of the System Tree, make sure you select to not add the systems when they exist elsewhere in the System Tree. This setting prevents duplicate entries for systems in the System Tree.
Unlike Active Directory synchronization, only the system names are synchronized with NT domain synchronization; the system description is not synchronized.
