I moved a licensed installation of IPMonitor 10 from a Microsoft 2003 to a Microsoft 2012 server. All devices are visible in the new installation but most of the devices are offline. When I do a rescan on a offline device the device is coming online. How is this possible? its not done to rescan more than 2000 devices. It's completely random witch devices are set offline. In the screenshot you can see servers in the same vlan with the same server settings, some servers are online en some are offline The offline servers are pingable from the IPMonitor server and snmp is configured well.
After a while when I select the offline device it says:
Based on the current display settings, this Group has no visible Members or Dependencies.
Kind Regards,
