SBS 2011 shuts down on it's own once a week!

Posted on 2013-05-28
Last Modified: 2016-11-23
If I had hair, I would pull it out!   This one is driving me crazy!   I have a new Dell 420 server running Windows SBS 2011.  The system was migrated into an existing 2003 enviroment and is running all 5 roles, hosts Exchange and Sharepoint.  There is another 2003 server acting as a communications server and backup DC.

My problem is the server shuts down on it's own about once a week with NO notice, NO event log entries, it just shuts down???   The Dell OSM shows "an OS shutdown" in the logs so I assume that it's Windows doing it.   There is NO scheduled events to shut it down.  We have removed AVG, disabled BUEXEC 2010 and any non-essential services with NO luck.

The logs are reasonably clean, nothing specific.  
The only role that the server is not performing is DHCP due to firewall issues.

Any help before I have to call my favorite software vendor (Microsoft) would be appreciated.

Have you checked it's not caused from the environment it's in like the UPS causing it or a power short in the server room. Is anything else turning off apart from the Server?
Does it happen at the same time and day each week?

Close the remote access port and see if still happens. Have you any users as administrators who could be doing it without understanding what they are doing when shutdown.

Try moving the Server to a new power source and start to eliminate some of the external possible problems since the Server appears to be clean and event error free.

Yes, we moved the power source to another UPS and straight to the wall.  No UPS software running.   I have not disabled RDP as we admin using it, but have changed the admin password.

Have you checked the raid controller logs for abnormalities and run a chkdsk on the drives ?
Perform some hardware tests on RAM and CPU.
Is the server in a climate controlled room or at least aircond?
Does the Server overheat, check fans etc...
Check PSU is functioning properly and not overloading.

Could it be possible one of your other servers is sending a command to the new dell server?
Do you have the luxury of turning off the other servers to do a test, so you can isolate the problem.

What are the events leading up to the unplanned shutdown?
Do you have a dump file to look at?

Have you actually run some tests for trojans instead of stopping AVG. Try running stinger on the Server as a start..  -  Scroll to the bottom after reading :) and download.

Silly question, have you registered the Server online

Good suggestions.  We have performed the basic Dell hardware check and checked through the hardware logs.  The server, when it shuts off, does it "gracefully".  

I do not have the luxury of running off the other server while we are trouble shooting.

I will run Stinger and get back to you on that.

Also, yes we registered the system online.

Ok, hopefully stinger does not report anything. Make sure you set the options before scanning with it.

A few other things to try to be sure:

Make sure you have the SBS box fully patched and any service packs installed.
Run SBS BPA and see if it reports OK.
Update the BIOS to latest level and any firmware on your devices.
Try resetting BIOS settings back to default - backup 1st.
Unplug any un-needed external devices ie: Ext HDD or any USB devices other than KB/Mouse.
Thoroughly go through the scheduled tasks and see what tasks run around the time of shutdown.
Left field on this one... - make sure you did not disable IP6.
Check that no Services are set to shutdown if they stop or have problems and check all services that are automatic have started.

Also back to the PSU, try installing your UPS software and visually see what the power usage is, this may save two birds without throwing one stone.

More great suggestions, I have tried most of them.   I have not updated the firmware yet, the box is only 2 months old, but I will.

As for running BPA, no issues.
IP6 = on
No services set to restart after failure.
I am not going to install any UPS software unit this is over.

Hi Rikklea

Have you had any shutdowns since the firmware updates?
Are you able to swap out the power supply to test?

What are the actual hardware specs of this Server?
A link would be beneficial..

Yes we have.  We called MS and had one of the techs look at it.  Turns out that there was a trust issue between the VM and the SBS DC.  VM's are not supported on 2011 and we knew that but I never would have guessed it would shut down the server.  Why would MS give you the software and let you install something if its not supported?

The only solution was one that MS presented to us.
