server 2008 Server Shutting Down

[Dan~]

Got a server which once a week will become inactive, if I look at it, it is running with the power LED on, but screen is black and mouse/keyboard completly unresponsive, so I have to hold down the power, then turn back on.

If I look at the Event Viewer it's not really telling me what's going on.

"The previous system shutdown at 18:26:18 on the 23/10/2011 was unexpected - Event ID 6008"

I've looked and from 17:00 to 18:11 (18:11 being the last event, which was "The WinHTTP Web Proxy Auto-Discovery Service service entered the running state")

The machine has had some warnings of Remote Installation software, I will try and rectify this.

Also this machine acts as the Hyper V server, so I've turned these off and will leave for a week or so to see if it happens again.

Not too sure what else to check

Make / Model of the server, age, anything of else that could be of use to us?

I'd check with the manufacturer to see if it's a known issue, and double check on BIOS updates

It's an HP Ml110 G6, only about 1 year old.

I've uninstalled software and made sure software via group policy doesn't get applied as it doesn't need it,

will check to see how things go

It isn't really helpful, but we have a server which does something similar. So we scheduled a reboot every night at like 2am, and we don't suffer from down time any more.

conflicting software, memory leak, etc.

this is not normal and is specific to your environment, please give more specifics or expect no one to answer this. IMO just install the server os, lock it down do not have it joined to the domain, have it a standalone server with no other function or software other than running hyper-v. You will have little issues doing it this way. Adobe shouldn't even be loaded or Java for that matter.
