Have toy checked the hardware, e.g. CPU, Fans, Memory ?

Is the Server on the HCL for ESXi 4.0 ?

When a ESXi 4.0 server reboots, often the logs are erased, they are not persistant.

the logs are in /var/logs/

vmkernel.log is the log you'll want to check

ESXi 4.0 is installed on Dell Power Edge 2950. When you say Check CPU, Memory? How do you check that? by opening the server??

Also when i logged in Server it gave me 4 options under View System Logs
3)Management Agent
4)VirtualCenter Agent

I went into all of those and it is zebrish to me.
Not sure how to check the logs you told me.
Is there any way i can copy the log files from server and attach it over here. Please tell me in details as i am no vise in this.

Yes, opening the server is a good idea.

Also check and run diagnostics.

Reboots are often called by hardware failure.

Has this just started to happen, or is this a new install.

Ok, I will run the Diagnostic test and see if it point out to something. It just start doing in now. No It was not updated recently.
