This evening while configuring a new Hyper-V Core Server 2012, even though I enabled the Remote Desktop option in the Config console, it still wouldnt play nice.
So todays tip - dont forget to enable the firewall rule. (Thanks to this post on Tech Net by Adnan Bhatti)
"you have to enable a rule in the firewall. Just type below in command prompt after enabling the RDP through CLI. "
netsh advfirewall firewall set rule group="Remote Desktop" new enable=yes
