Cannot get Folder Redirect to work on RDS Server

Question

OK here is what I am trying to do..
Windows Server 2008 R2 Remote Desktop Services
I want to redirect all user profile folders (Desktop, Music, etc...) to a remote share 
\\server\share  to which the share is actually only giving Read-Only rights.  Except for Documents to which they can save there on the RDS Server itself.
I had a server drives hidden (A:, B:, C:, D:) hidden so they could only save to network shares and their local computers.  However, the people in the UK complain that saving to their local computers is just painfully slow  (the RDS Server is in
the US).
So, Now I'm only blocking the Server C: drive.  I have a SUBST going on pointing B: to the user profile folders (needed for a different application anyway).  I need to have the "B:\Documents" open for these guys to save to however, I
want to block saving to any of the other profile folders.
What I tried to do was to set a GPO up like below:
Computer\Admin Templates\RDS\Session Host\Profiles
Set path for RDS Roaming User Profile Enabled (pointing to
\\Server\Share)
User\Windows Settings\Folder Redirection\Desktop
Basic (Redirect everyone's folder to the same location)
Path \\Server\Share
Grant Exclusive rights to Desktop - Disabled
Move contents to the new location - Disabled
Apply to older systems - Disabled
First, is what I am trying to do even workable?
Next why can't I get it working.

Hi,
>>I want to redirect all user profile folders (Desktop, Music, etc...) to a remote share 
\\server\share  to which the share is actually only giving Read-Only rights.
To redirect user’s folders to a network share, the minimum NTFS permissions of the root folder required by the users is
List Folder/Read Data, Create Folders/Append Data - This Folder Only.
Regarding security recommendations for Folder Redirection, the following article can be referred to for more information.

>>Move contents to the new location - Disabled
For disabling this setting, the existing data in the folders will not automatically follow the folders when they are redirected to the network location.
>>I need to have the "B:\Documents" open for these guys to save to however, I want to block saving to any of the other profile folders.
After redirecting the folders, if we really want to do this, as an administrator, we can take ownership of the user folders to where user’s profile folders are redirected,
and then edit the corresponding NTFS permissions.
