Connect to Hyper-V guest via RDP, Wake on RDP

Hi all,

i am using Windows Server 2012 and integrated Hyper-V to virtualize some old machines and a few new ones to replace physical PCs.

Some of the machines are only needed a few times. I am able to connect to the VMs via RDP just by IP as if you would connect to a physical machine - works. But how can I wake up the machines via RDP? May I adress the machine over the server, which wakes up the machine and redirects me to it?

Thanks,

Hans
