My config files state the name of each computer, using Ghostwalker to change the sid. Each PC needs a config file attached to it from the clone task. My machines reflect the lab they are in and then a number for the machine ( ie WB365-01,WB365-02 etc for 40 machines) If I start from scratch creating config files for each machine in each lab, there are over 500 machines I need to creat a config file for. I do not use sysprep, because my solution using Ghost Walker is completely no touch for all the machines.
