ZCM 10.3.1 on SLES

We were trying to image a new model of computer, Lenovo M91p, and having problems getting PreBoot service to launch. Thought perhaps the latest PRU would fix it. So downloaded and deployed the June 2011 PRU, and rebooted the server. Server sent this message via email.
"Error: [6/2/11 2:26:29 PM] Loader.SettingsRefreshModule SettingsModule.SettingsUnknownError An internal error occurred while trying to refresh the system settings."
At console the zenserver process status is "dead". I issued a zenserver restart but still "dead".

What happened and how can I fix it?

I installed this box a year ago just to test out Zenworks Configuration Management and this is the first problem we've had.
