Configuring Hyper-V for the Cristie Appliance

2012R2 based Hyper-V server shows Authentication error
Due to changes to Microsoft Hyper-V, the following changes are required before you can add Hyper-V to the Cristie VA. Attempting to discover Hyper-V without making these changes will result in Authentication errors.

The following steps are to be run on your Hyper-V Server and not the machine running the Cristie VA:

  1. Ensure server service is running

  2. Ensure remote registry service is running

  3. Navigate to control panel and select Administrative Tools -> Local Security Policy

  4. Navigate to Security Settings -> Local Policies -> Security Options

4a. Double click “DCOM: Machine Access Restrictions”, edit the security and add the required user with permissions for “Remote Access”

4b. Double click “DCOM: Machine Launch Restrictions”, edit the security and add the required user/group with permissions for “Local Launch” and “Remote Launch”

  1. Navigate to control panel and select Administrative Tools -> Component Services -> Computers

5a. Right click My Computer and select Properties

5b. Click the Com Security tab

5c. In the Access Permissions section, click Edit Default and add the required user with permissions for Remote Access

  1. In the Launch and Activation Permissions section, click Edit Default and add the required user/group with permissions for Local Launch and Remote Launch

The following steps require you to open and run Regedit. If you are not familiar with this, please forward these steps to your systems Administrator.

  1. Open Regedit

  1. Select HKEY_CLASSES_ROOT

  1. CTRL+F and search for 76A64158-CB41-11D1-8B02-00600806D9B6

The key found should be WBEM Scripting Locator

  1. Right click and select Permissions

  1. Change the owner to the Local Administrators group

  1. Add the user/group required with Full Control permissions

  1. Click Apply

  2. Change the owner back to TrustedInstaller (you may need to set the user to NT Service\TrustedInstaller) (see step 5 for further instructions)

  3. Restart the Remote Registry Service

You can now add your Hyper-V server to the Cristie VA as you usually would.
