After you install and deploy Essentials 2007 and begin managing computers or network devices in your enterprise, you might also want to manage additional computers over time to accommodate growth and other changes in your organization.
If you enable this feature in the Feature Configuration Wizard, one of the Essentials 2007 installed Management Packs performs discovery once each day. During that process, Essentials 2007 searches your network for computers that have not yet been discovered. If new computers are found, Essentials 2007 automatically installs an agent on them so that they can also be managed.

In the Authoring pane, click Rules.
In the Look for box, type Scheduled and click Find now.
