You can manually install an unmanaged agent on a Windows computer. After you install an unmanaged agent, you can make changes to its configuration. For more information about reassigning an unmanaged agent to a different central computer, see the NetIQ Agent Manager User Guide.
You must first authorize the new unmanaged agent, after which the agent sends a heartbeat to the central computer. Sentinel Agent Manager sends the unmanaged agent configuration data, and at the next agent heartbeat, the agent sends configuration information back to the central computer. Sentinel Agent Manager then assigns the new unmanaged agent computer to all applicable device groups and displays the agent in the Agents view.
For more information about configuring the heartbeat interval for agents, see the NetIQ Agent Manager User Guide.
