Why is the Auto-Discovery working only for half of my devices?

I tried 4 times, auto-discovering my entire network. But each time auto-discovery works only on 60% devices with default 7 sensors added automatically, while other 40% devices discovers only 1 ping sensor. Why remaining 40% devices not auto-discovering them fully?

What will be the reason & resolution for such issue. Need Help.

Hello,

if PRTGs Auto-Discovery is only able to create a Ping Sensor for certain devices, then either these are 'special' devices not known to PRTG, or there is a firewall (or something similar) blocking all other requests, like WMI or SNMP, from PRTG to those devices.

Best Regards.
