What does ZCM do after booting new image?

I am used to using Zen 7 for imaging, and after booting I would see a
notice on the screen from Zenworks saying wait. After a few minutes with
a lot of hard disk activity Zenworks would reboot the computer. I assume
this was being done by the Zenworks Agent and it was changing the sids.
It certainly changed the computer name for me. If it was a new computer
I would just remove the imported workstation from the directory and
reboot and it would be imorted again with the new name.

Am I right in believing that that ZCM is quite different from this. I
have had one attempt on Vista with little success.
