The Install/Uninstall Agents Wizard can also be launched from several other places in the MOM Administrator console, including: the root Microsoft Operations Managernode in the Navigation pane, the Administrationnode, and the Computerssubnode and all of its children. If you want to launch the wizard from these other locations, click the Install/Uninstall Agents Wizardlink.
Although agents are installed on specified or discovered computers by default, the Install/Uninstall Agents Wizard queues agent installation in Pending Actions(in the Navigation pane of the Administrator console, below the Administration/Computers node.) After an interval, the agents are installed and the discovered computers appear in the Agent-managed Computers list. To see this list, expand the Administration node down to, and including, computers. Click Agent-managed Computers. The discovered computers are listed in the Detail pane.
