256986 Description of the Microsoft Windows registry
On Windows Vista-based computer, you cannot use Registry Editor to load a registry hive file that is on a shared network resource. You receive the following error message:
Cannot load \\HivePath\FileName: Access is denied.
This problem occurs even if the user account that you use is granted Full Control permission to the registry hive file.
This problem also occurs if you use another utility to load a registry hive file that is on a shared network resource, and the utility uses the RegLoadKey API.
This problem occurs because of a design change in the RegLoadKey API in Windows Vista.
