Hi, My server had a reboot. The previous system shutdown at 8:12:19 AM on 3/7/2010 was unexpected. I have checked the eventlog but i couldn't able to find the logs for the cause. Dump file also not created. Role of Server : Exchange 2003 Please help me. Regards, Karuna Karuna

Is it a virtual server?

Hi, Please also try to check whether there are any hardware issue. Best Regards, Vincent Hu

Hi, It's not virtual server. I don't see any hardware failure logs. Karuna

Same problem. It was averted by upgrading the UPS (uninterruptible power supply) the unit was attached to. Basically it was a power failure and this is why the dump logs were not created. Clean power = happy system

Whats the server brand and model?
