We have a number on workstations in one area of our university whose desktop policies do not refresh following build/rebuild.
Workstations are members of a group and a policy package is associated with that group which deploys printers and makes some tweaks. The workstation can be rebooted any number of times but the policies don't appear. Run wmsched and click "Refresh" and there they are.
Is there a means of forcing the workstation to refresh its policies (other than by manual intervention) or troubleshooting what might be going on?
We're using Zenworks 7 and Windows XP SP2 and SP3 clients.

Thanks in advance,
