Problem connecting to Hyper-V 2012R2 Core from a Windows 8.1 computer

Hi there,
I am trying to set up a server with Hyper-v core (windows 2012 R2 version of Hype-V). I already installed Hyper-V in the machine, gave it a name, a fixed IP with the DNS information, connected it to our domain and configure the server to allow remote connections.
When I open Hyper-V manager in my pc (running Windows 8.1) and try to connect to that server,  the Virtual Machines space  shows that Hyper-v trying to connect to Virtual Management Service for a long time and after it fails it displays: RPC server unavailable. Unable to establish communication between "the server" and "my laptop".
Any idea is highly appreciated.
Thanks!!!

Hyper-v hasn't changed much in this regard since v1 if the management station is not in the same domain as the hyper-v server. You have to jump through some extra hoops. There are plenty of blog posts on the subject, but I find this one easy to follow:

Hi

Can you check if WMI is allowed it the hyperV machines firewall?

Cliff, thanks for your answer. Hyper-V server and the management station ARE in the same domain and subnet.

Patrick, thanks to you as well but I fall short to understand you.

And you are logging with a domain admin account, NOT a Microsoft account on the management station? Even if the MS account is linked, I've seen credential issues when it comes to admin privileges.

Hi

I found many occasions in the past where i could not remotely manage servers where allowing WMI was the solution.

Cliff, I am logged in using domain admin credentials in the management station. Both boxes, the management station and the server (hyper-v host) are in the domain.

I temporarily put the management station firewall OFF. In the hyper-v host server I configured the computer name, the domain, the network settings and the remote access. Is there something else that I think I should do on that server Patrick?

The management station is not an issue, if you want to trial and error disable the hyperV firewall and reconnect, what happens?

Hi Patrick,
I went to Powershell in the Hyper-v Server and ran the following command

netsh advfirewall set allprofiles state off

Got an Ok back from the command prompt. Still getting the same results.

I tried another computer with Windows 7 Pro that I borrowed for a moment and I installed the RSAT tools and enabled Hyper V. From this W7 computer I am able to connect to the server. The conditions are the same. The Hyper-V host and the computer are both in the same domain and same subnet. Have anyone heard of any problem of using hyper-v manager from a W8.1 management station?
I cannot simply change my computer for a W7 so I need to get this to work. H E L P !!!!

Hi there,

After battling this for way more than expected without finding solution for my problem, I decided to reinstall the OS in the management station (Windows 8.1). I was forced to install Windows 8 first and them upgrade to 8.1 but it was worthy. I am now able to access the Hyper-V server and create virtual machines on it. I have no clue what the problem was.  I would have been very good to know what was causing the problem but I did not have more time to play with it. Thanks to all for the support.

I did not found the cause of the problem. I was able to solve it by reinstalling the OS in my computer. Nobody could offer a real solution.
