Devices with agents landesk are not in my network view ?

Hi

I have a problem with the discovery of new pc. Indeed, the deployment of LANDesk my agent is going well, but I do not see the pc in my network  view and all devices;  while the PC has good agent?
I am forced to click on each device of inventory scan to see in my network view?

my devices is not considered a managed because the LDMS agent has not send an inventory scan back to the core server

Thank you for your help
