Enabling Remote Access to Device Manager

Run MMC, then select File > Add or Remove Snap-in > Group Policy Object Editor, then select the Hyper-V Server 2008 R2 computer.

Once in the Group Policy Editor, it took me a while to find the PnP setting. The correct location is:  Computer Configuration\Administrative Templates\System\Device Installation\Allow remote access to the PnP interface.

Run gpupdate on Hyper-V Server 2008 R2 computer.
