    [BASESRV] Strengthen default permissions for DOS devices
    
    This is linked to previous work done on DOS devices creation
    in basesrv. If this DWORD is not set (or 0), DOS devices will
    be created with an ACL that make the symlink readable by any
    and modifiable by any.
    With protection mode set, the symlink will be still readable by
    any but not modifiable by anyone but the owner.
    
    This should also affect some objects managed by session manager.
    
    By default, on W2K3, that protection mode is set.
