HyperV Error Access Denied Unable to establish communication between HyperV and Client

Hyper-V Error  Access Denied Unable to establish communication between Hyper-V and Client

Here is the fix


Virtual Machines

Access denied. Unable to establish communication between ‘Hyper-V Server’ and ‘Hyper-V Manager’.

This is puzzling since the workstation has been connected to this particular Hyper-V server many times using other network profiles. The profile we created for the Microsoft folks was seemingly giving us the connection issue.

The fix took a bit of searching to find and needed to be accomplished on the Windows Vista system where the Hyper-V Manager was installed:

  1. Close the Hyper-V Manager
  2. Click Start and type: %windir% [Enter].
    • A Windows Explorer window will open to the Windows directory.
  3. Type: dcomcnfg in the Search Windows field at the top right hand of the Explorer window.
    • You will see the following in your search results:image
  4. Right click on dcomcnfg and Run As Administrator.
    • Authenticate with the local admin credentials if UAC prompts for credentials, or Continue if it does not.
  5. Open the Component Services node, then the Computers node, then right click on My Computer and click on Properties.
  6. Click on the COM Security tab.
    • You will see the following:image
  7. Click the Edit Limits button under Access Permissions.
  8. Enable Remote Accessfor Anonymous Logon
    • Before and after shot:image
  9. Click Apply and OK.
  10. Close the Component Services console and the Windows Explorer window.
  11. Start the Hyper-V Manager and continue through the UAC.

The virtual machines, if any, will show up in the Hyper-V Manager console after that.

Add Storage to Hyper-V core server

Here’s a high-level step-by-step on how I recommend installing and partitioning your Hyper-V Server 2008 box:

  1. Install Hyper-V Server 2008.
    When you’re asked to partition your system, delete all partitions on the disk and create a new 4 – 12GB disk to install Hyper-V Server 2008 onto. The disk really does not need to be any bigger in size.
  2. Find the appropriate disk.
    After logging in for the first time choose option 13 in HVConfig.cmd. This will open the command prompt if one isn’t already opened in the background already. Type the following command to list the disks in your system:

    DISKPART> list disk

  3. Convert the disk.
    When you only have one disk in your system you would choose to convert disk 0 to a dynamic disk:

    DISKPART> select disk 0
    DISKPART> convert dynamic

  4. Reboot.
    Reboot your server to convert the disk.
  5. Create the volume for the Virtual machines.
    You can now create the volume that spans the unused space on your disk. Use the following commands:

    DISKPART> select disk 0
    DISKPART> create volume simple

  6. Find the appropriate volume.
    After you created the volume you need to format it. Find the right volume by typing

    DISKPART> list volume

  7. Format the drive and assign a drive letter.
    The last step is to format the volume with NTFS and assign a drive letter. Use the folloing commands:

    DISKPART> select volume 2
    DISKPART> format fs=ntfs label=”Hyper-V Guests

    assign letter=h
    DISKPART> exit

Hyper-V Remote Management: You do not have the required permission to complete this task

You will hit this problem when using the Hyper-V Vista management tools connecting to a remote Windows Server 2008 machine with the Hyper-V role enabled, and where both machines are in a workgroup (or in a domain environment where you genuinely don’t have access )

(On Client and Server)

Make sure you are using a username and password which matches between the client and the server

Cannot connect to the RPC service on computer ‘ Make sure your RPC service is running

Remote HYPER V MANAGER / HYPER V MMC Error ” Cannot connect to the RPC service on computer ‘’. Make sure your RPC service is running”
Yes i too had the same RPC issue, when both Hyper-v-server and hyper-v manager was on the same domain, there is no issues at all but once the hyper-v server and client brought to the workgroup environment the issue starts, one of the solution is to edit your hosts file which is under C:WindowsSystem32driversetc

add the following entry


This would simply sort the issue.
