We have a selection of top level folders:
E:\Data1 E:\Data2 E:\Data3
The permissions are simple - the default
SYSTEM Full Control, some security groups allowing Modify and the
LOCAL SERVER\Administrator group Full Control. There are no DENY, only ALLOW permissions.
I have a user account that is a member of the local Administrator group mentioned above. However, when I access the folder, the UAC prompt appears and says it needs to add permissions before I can access the folder. An explicit entry is added for this user account and now I can access the folder.
But why? I am a member of a group that has full control, why is it prompting? The folder is set not to inherit permissions from the parent folder so there aren't any weird permissions inheriting from parents folder.
