We are using Dell's Latitude 2100. We have replaced the 160 GB hard drives with imation 32 GB m-Class Solid State drives. We are using Zen Desktop Management Agent They Image just fine, but they will not register with Zen. I have tried running zwsreg in command line to manually get them to register, but when you reboot the data is gone. When you run ziswin you get: There is no image safe data. I have also tried PXE booting into zenimg and when I get to a prompt running zisedit to manually edit the data. It will not save. Anyone have any Ideas?
