What we need is a wake-on-lan function for nightly client pc boots.
This would allow us to install certain updates when the computer is not used by a end user. the clients reside in several different VLAN's, which means that we probably need to send kind of a "unicast magic packet" for booting them instead of taking use of broadcast.
The wake-up frame is sent using broadcast. Since we use VLANS in our network, the broadcast won't be transferred to the client computers in other networks than the one where the DSM server is.
It requires a configuration policy setting under
dsm\common components\caf\wake-on-lan\WOL: broadcast = Unicast
or
dsm\common components\caf\wake-on-lan\WOL: broadcast = Broadcast + Unicast
Then it uses unicast.
