As i know in WDS, for each Image i can assign an unattend file. In that file i can configure ComputerName. I could change that file everytime i need to install a computer, but if i want to install 2-3 or more computers in the same time? let's just suppose that on a night there is a power failure and in the morning a need to install as soon as possible all workstations. I don't want to wait until first one is installed, modify the unattended file and start the second installation.
