I upgraded to Win8.1 a few weeks back and since then when I wake up my PC lights-out does not wake up the server, I shutdown my PC last night and when I turned it on today it still didn't wake the server. The settings on the server are set correctly and allow the PC to wake up the server upon resume or boot.
Another PC on the network currently running Win8 has no issues, I removed it and installed it again but that didn't fix the issue.
