When monitoring Volume/Disk Space on the Windows 2000 machines, the values do not update. Why?

Windows 2000 SP3 machines will update the Volume/Disk Space values appropriately. Windows 2000 machines without SP3 update the MIB only at reboot. We recommend installing the latest Service Packs on the machines in order to view the appropriate Volume/Disk Space values.
