Since we upgraded to ZCM 2017, weve only be able to use Wake On LAN (WOL) to switch on less than 20 devices at once. If we try and target more than 20, none are woken. If we select a sub set of them (10 of the original machine selected, for example) they wake without any issue. We have multiple subnets and VLANs on multiple physical sites, with satellite servers at each site. It all worked as expected with 11.4 and we could wake all machines at each site (100s of machines at a time).

There doesnt appear to be a lot to configure in ZCM 2017 (Configuration -> Device Management -> Wake-on-LAN). Is there any setting anywhere else or any log files I can check?

Many thanks,
