Hi guys,
Firstly, I'm a huge fan of this Add-In. It's extremely useful, when it works.
My Macbook (10.8.3) can suspend my WHS 2011 server, but cannot WoL currently. This was working until I unplugged my LAN cables and moved them around a little the other day. This has happened before, just after installing LightsOut on my Win7 workstation.
I have tried uninstalling the Launchpad and LightsOut plugin completely, and reinstalling. Restarting both my Macbook and WHS2011 machines inbetween each step.
Are you able to help diagnose what might be going on here.
Adam
