Changing this setting is NOT necessary for remote management in a domain environment, but it is in a workgroup environment

I was trying to connect from primary test box to my hyperv core test box via the Hyper-V MMC management tools, I kept getting „Access denied. Unable to establish communication between Client and Server“.

From the command prompt of your ‘Client’ can do this by typing: „DCOMCNFG“ in the run-command in Windows.

1. Browse trough to: „Component Services → Computers → My Computer“.
2. Open Properties for „My Computer“ and select the COM Security tab.
3. In „Access Permissions“ area click the “Edit Limits”-button.
4. Select the “Anonymous Logon”-group and make sure the “Remote Access” is set to Allowed.

Now you client tools should connect successfully to the servers Hyper-V management.
