Well have you got it on a UPS?


It could be something as simple as a bad power supply from the mains causing this problem. Also if it's been in service for over 6 months it might be worth while removing the server pulling the covers and cleaning it out if it is full of dust and Crud. Either of these could be causing the shut downs that apparently have no explanation.

If the CPU is running high what temp is it running at?

There should be a utility included with the system or M'Board that will give you the CPU/s Temp, Fan Speeds and critical Voltages launch this and monitor it for a while it would be particularly nice if you where watching it when the unit shut down unexpectedly it just might give you a clue as to what is happening.
There are a couple of things to look for the CPU/s temp, the CPU/s Fan Speed and the 5 V rail if it is going under 4.8 V there is something seriously wrong and you'll have to work out the fault before you have any serious damage done.

When the 5V rail gets down to 2.8 V or lower you will be kissing away your MBR's and you'll have what the computer will tell you are blank HDD's believe me that one is no fun at all I hope you have a current backup ready.

I you are concerned about a Virus restart in Safe Mode and run an AV Scan that way you are more likely to pick up any infections and be able to remove them.

It's also possible that you have picked up a Memory type Virus/Infection which is loaded into RAM on start up so it is very hard to get out of the system. If you have Norton's you can always set the unit to boot from the CD and run an AV Scan from the Norton's CD which will remove any nasties like Memory Infections.

Also if the CPU usage is High what is the traffic on the network like? You should check this one out as well just to make sure that nothing funny is going on there.

Well, no dust or nothing... Just that it restarts at random. And the APC is in good shape... And it very slow.. High CPU cycles... What could it be?

I agree with Hal on this one.
One other possibilty it heat. If the CPU gets too hot it will restart on you. Make sure you have really good airflow thru the server.

If this is a Dell or HP type server I would load their diagnostic tools and monitor it for a while.

Good luck

Two questions :

1. Have you recently applied SP1 to your server ?

2. Are any of your users or yourself using Terminal services on this server for any reason ?


There are some known issues with SP1 and TS that cause a stop error ab.

One of the main ones :
http://support.microsoft.com/?kbid=901150

If that doesn't work for you, you will have to contact MS and ask for the private hotfix version 6, dated aug 4, 2005 (version 5.2.3790.2500)

This is all assuming you have SP1 and TS.
