Vista - Unable to disable offline files via Group Policy

I'm having the hardest time disabling offline files.
This is what we have:
Document, My Desktop and a few other folders are on Folder Redirection.
I have the following settings on my OU that may affect offline files:
Allow or Disallow use of the Offline Files Feature: Disabled
Phohibit user configuration of Offline Files: Enabled
Always wait for the network at computer startup and login: Enabled
Administratively assigned offline files: Disabled
Remove 'Make Available Offline': Enabled
Do not automatically make redirected folders available offline: Enabled

I have followed instructions on this KB about op locks:
http://support.microsoft.com/kb/296264 to no avail.

Users still have the ability to enable/disable offline files and by default
the settings are set to have offline files enabled.

I want to disable it. What do I do?
