unable to obtain id on windows 2012 hyperv with gui

[iceman1977]

Hi. I have recently installed a new Windows Server 2012 r2 standard with hyper-v role enabled, with upon it a vm windows 2012 r2 standard.
Both From the hyper-v and from the vm, teamviewer is unable to connect (it seems that it doesn't even try to). On both OS windows firewall is completely disabled. Inside the same lan, all the computer are instead able to use teamviewer inbound and outbound.
There are some limitation with hyper-v or Windows Server? Thanks in advance.
