I've got a large batch of HP DC5100. They refuse to enter ZEN imaging in
either manual mode or automatically. They simply go on as if there's no
work to do, and they localboot. In order to image them, I need to go into
windows and clear ZISD, at which point it will allow imaging to start either
automatically or manually.

Servers are HP6. Clients have HP4 Agent. Are there any known issues, or a
way to fix this easily without having to clear ZISD manually on every
