Hyper-V Svr2012 Win8: Operation on computer {servername} failed

Hi,

Weird one:

We have a hyper-v server 2012. I'm trying to connect my windows 8 hyper-v manager to it.

Currently I am connected and can change settings (by right-clicking the hostname in the manager) and even create, export and import vm's, BUT in the Virtual Machines Pane, no vms are listed. I'm greated with the following msg instead:

The operation on computer {server hostname} failed.

I've configured dcom on both machines, WMI open on both firewalls. My user account has been added to the server and added to the hyper-v administrator group on both machines.

What am I missing?
