  5. To allow a domain administrator to access the folder, first, ensure that a valid domain is specified in the From this location box of Figure 219.

To change this specification, use the Locations button in Figure 219. Then, enter the name of the local/domain administrator in the Enter the object names to select text area, and click the ok button.

    • Key Name : LocalAccountTokenFilterPolicy

    • Key Type : DWORD (32-bit)

    • Key Value : 1
