On Windows 8 or Windows Server 2012 you can install the Hyper-V Management Console and use it to connect to a server or client running Hyper-V Services.
Microsoft has the basic configurations covered at this address;
There is a rather important detail missing though. To connect to the Hyper-V Service running on a different machine, you need to run the Hyper-V Manager using a local account.
Now if you are like me you are thinking to yourself "I am using my local account!" Well you may not be. If you chose to use a Microsoft account when you installed Windows 8, then you are not using a local account.
So make sure you have a local administrative account on both the Hyper-V Server and the Remote Management machine. Hold down the Shift key and right click the Hyper-V Manager link and select to "Run as different user" and use your local account.
Have a read through the community comments on the bottom of the Technet page for more details.
