Resetting folder permissions from a parent folder forces subfolders to exactly mirror those permissions. This simplifies the permissions status of these folders, making them more predictable
Start the Server Administrator and click the VFS tab.
In the left window, select the top level folder that has the permissions you want for its subfolders.
Right-click the folder and choose Reset Subfolders.
Click OK.
Note
Resetting folder permissions from a parent folder differs from manually changing the inheritance values of subfolders because in a subfolder you have the option to either mirror the parent folder's permissions or to keep permissions for any new Users and Groups you have added while also mirroring the permissions for all Groups in the parent folder.
