How to remove full control from users redirected documents folder?

Hi,

I'm migrating our users from Windows XP to Windows 7 at the same time changing the mapping of their Documents folder from a Windows 2003 server to a Windows 2008 R2 server.  I've noticed that on the new server the users get Full Controll over their Documents folder.  This is an issue for us because we've had users block the Administrators from their files, which isn't appropriate.

I'm more familiar with Windows XP/2003 secruity structures, how can I remove the Full Controll right on these folders in 2008 R2?  A step-by-step procedure or direction to a tutorial would be great.

Thanks in advance,

Linn
