Workgroup Manager - machines not picking up preferences
i have created my computer groups in Workgroup Manager and added the client machines to the correct groups and set preferences.
The issue is that none of the machines are picking up the preferences, i have added the machines by their mac address.
Is there any way i can force the prefernces through similar to gpupdate on a windows server.
Thanks
MacBook, Mac OS X (10.5.6)
