I noticed that from time to time Zenworks would stop pushing policies into
the computers at my school. Now I realized that it is because the DHCP
changes the IP addresses of the computers. Then, since the IP address
changes on the computer but it still has the old one on the workstation
object, Zenworks does not find the computer and thereby pushes no policies.

Is there a way for the Workstation Import service to update the information
when the IP changes?
