we have been using zam for few month, we did the uprage fro 7 to 7.5.
Our network is composed with 650 workstation running windows 2000 sp4
with the zam client and alos for almost half of them we are using :

Deep Freeze instantly protects and preserves baseline computer
configurations. No matter what changes a user makes to a workstation,
simply restart to eradicate all changes and reset the computer to its
original state - right down to the last byte. Expensive computer
assets are kept running at 100% capacity and technical support time is
reduced or eliminated completely. The result is consistent trouble-
free computing on a truly protected and parallel network, completely
free of harmful viruses and unwanted programs.

So my question is what should we do to get the most accurate data for
our asset and inventory in the case were deep freeze is running and
reseting the system at every reboot....could you suggest a processs to
make it more accurate.
