Group Policy Folder Redirection Problem

Hi, Im trying to redirect laptop users my documents folder to a network share through group policy folder redirection. The server is Windows 2003 and the clients are Win Xp professional SP2. I have setup a network share and given the security group containing the laptop users full control over it. In group policy windows configuration folder redirection I have changed the properties of my documents to give the security group rights to create a folder under the root path for each user and specified the path to the network share. This policy has been applied. However when users of the security group logon their my documents folder are not been redirected to the network share and no subfolders are been created there. Any ideas as to why the folder redirection is not working. Thanks.
