Task Manager doesn't show total processor time, it only shows the root partition's processor time. Take a look at the following article for information on how to determine the aggregate / total processor usage:

Processor:

Once you have an idea of the overall system capabilities and configuration though the “Hyper-V Hypervisor” counter set you will want to monitor the processors on the system. The most important counter set to monitor is the “Hyper-V Hypervisor Logical Processor”. This counter set allows you to determine how much of the physical processor are being used. The virtual processor counter sets only show a slice of the “Hyper-V Hypervisor Logical Processor”.

To connect using Hyper-V manager from a workgroup machine to an Hyper-v domain member server you also need allow anonymous DCOM remote access.

There is a tool from Microsoft that configues automatically all the necessary things for you: Hyper-V Remote Management Configuration Utility.

If this not work i would recommend you to check the Windows Credential Manager of the client machine looking for bad entries. If you are not sure, delete all of them.

And finally, off course could be a really RPC error, the RPC error could be failing in your server. For be sure that it is not the issue connect to the server using MMC with other Snap-in as example Local Users and Groups.
