We have created an image with all the correct settings, we then use
sysprep so that on restart all that is needed is to enter the computer
name and all would be finished.

The problem we have is that after the images has been downloaded and has
gone through the sysprep process, next time we logon it has lost all the
advanced DNS settings, the computer name has been made up by zenworks, and
the server has been registered to the incorrect suffix.

we do not have the zenworks partion loaded on the machines, does anyone
know what could be resetting these?
