We are currently testing a free version of OpManager (Build number 6003) in your School to supervise our network. Test is done with a Windows 2003 Server, a management station with XP Pro, a 3Com SuperStack3 4226T Switch and a Cisco Catalyst 2950 Switch.
But I have a problem when I add a device in the Admin page. I can add the device but I don't see the device when I click on his snapshot in the Home page. I saw that the device is listed in the "All devices Inventory Report" but not in the Snapshot.
