It is not possible register any Windows Shared nodes (WIN_GENERIC role), the error appears:
Host cannot be registered because there are no servers registered in POA with WPE and FDC roles.
The correct sequence is to:
Deploy AD Controller
Register WPE role node in POA (Deployment Director > Server Manager > Hardware Nodes > Add new node and select the required role)
Register FDC role node in POA
Register Windows Shared nodes (WIN_GENERIC role)
