Win 7 x64 - sharing drive and folders within

Hi all,

Previously, I have a Windows XP laptop that acts as a "file server" for multiple users. I allow network access to the drive and folder as follow:

1). Entire drive (i.e. USB connected external HDD)
Access by mapping to "\\ComputerName\Z$" and login as the Administrator

2). Specific folder (i.e. "Music" folder in the USB connected external HDD)
- First, create a local NON-ADMINISTRATOR account in the Windows XP laptop say, "Bob"
- Right-click on the "Music" folder, select sharing and add "Bob" under "Permission". I did NOT add anybody else as the Administrator always have full access to the drive AND the folder inside that drive
- Access by mapping to "\\ComputerName\Music"

In the above instance, I can still access the "Music" folder remotely (network map) as Administrator.

However, in Windows 7, this does not work. Unless I add the Administrator account in the "Music" folder sharing permission, only "Bob" can access that folder, even though I have Administrator Full Access for the entire Z: drive.

Moreover, even when I access the "Music" folder directly (not through the network) while sitting in front of that computer, I get "Access restricted" message (!!!).

So the issue is:
- The permission for a drive does NOT propagate in the above instance
- Even when accessing the machine physically, I can get "locked out" of my own folder.

Any ideas how to replicate what I did in Windows XP to Windows 7?

NOTE: I do NOT use Home Group as there is a mixture of Mac and Windows machines at my home.

 

Any ideas?

 

Firewall settings are the only thing that come to my mind

cheers ...
