your right, there a number of powered off vms. there is at least one windows server that fit the criteria. i confirmed by looking up the resulting mac addresses. the network label on the vm has "org management network". its nic 2 on the VM, not sure if that matters
this is what i used.
i get results with this
get-vm | get-networkadapter | where {$_.networkname -like "*org*"} (using a different network name)
not with this.
get-vm | where {$_.guest.osfullname -like "*windows*" -and (get-networkadapter -vm $_.networkname -like "*org*"}
thanks in advance
