I'm trying to create a manged pool of personal desktops in Hyper-V. When I run the wizard I get the following error: "Failed: The provisioned virtual machine could not connect to its primary domain".
Server 2012 R2 was installed on the server, and the Hyper-V role was added, and called HV1. Two instances of Server 2012 R2 were created, one was set up as the Domain Controller (DC), called DC1, and the other as the Remote Desktop Services installation (RDSI), and called RDSI1. The RDS was installed according to this step by step tutorial
The two Server 2012 R2 installations (HV1 and RDSI1) were joined to the third DC (DC1) one.
At this stage I attempted to create a collection of managed personal desktops, and am getting the above error.
The template I'm using is Gen1 (I tried Gen2, but Hyper-V said that they can't be used for a managed pool) Win 8.1 Pro sysprepped image (Sysprep /generalize /oobe /shutdown /mode:VM). I've created a VM from that image and it connects to the Internet, can run Windows Update, etc.
