I have a lab of 30 Optiplex 755 Dell Desktops. I made and image and had no problem getting it to boot into PXE and using Zen imaging to upload the image to the server. I then hooked up another 755, booted into PXE and Zen imaging. I then pushed out the image on the server to the other machine. It says it successfully finished, and then when I restart the machine, it gets to the Windows XP loading screen and then just reboots.

I also tried it doing a multi session and it did the same thing. Any suggestions on what might be wrong, etc?? Thank you in advance!
