The system started resetting itself exactly every 2 hours. These are the messages in the iLO2 log:

Informational iLO 2 03/07/2010 20:40 03/07/2010 20:40 1 Server power restored. Caution iLO 2 03/07/2010 20:40 03/07/2010 20:40 1 Server reset.

It's not an ASR reset (that would show in the log) Redundant power supplies, swapped but no change. Turned off all virtual machines (i.e. now only running hypervisor) but not OK Boot HP smartstart diagnostics disk, ALL OK Diagnostic disk reports no errors Went back to booting Hypervisor and the problem is back.

Seems the hyper-V system disk has got a time based program (virus) causing the reset. I thought the hypervisor had a small attack surface and should be OK. All virtual machines (SBS2008, Win7 and Win XP) and network computers are protected with TrendMicro WFBS.

I am about to rebuild the disk (I have backups) but wondered if there were any suggestions to try first???
