Does anyone know how to read/write the offline folder settings for shares on Windows Server 2003?

I have managed to enumerate the shares using the following:

Code:
 
$objWMI = GetObject("winmgmts:{impersonationlevel=impersonate}!//" + $Server)
$shareList = $objWMI.ExecQuery("select * from win32_share where type=0")


I would like to be able to set these shares to not allow users to mark the data for offline use (a new feature of Win2k3).

thanks,
Michael.
