Recently installed a new WHS 2011 on my network to replace one. I've installed the connector on each machine and the add-in downloaded and installed. However, even though I have Suspend chosen after backup in Lights-Out the clients will not suspend. If I do a manual Standby in Lights-Out, the clients will go to sleep.
On the old server which was running Windows Essentials 2012, the suspend worked on the clients.
Not sure what I am missing 
. Any help would be appreciated.
