Why is my Windows 2008 R2 Server restarting at same time every night?

At my place of work we have two Windows 2008 R2 servers, and one of them has started to restart itself every night at 12:13:14 AM. There are no scheduled tasks that could be causing this, nor is it a Windows Update restart.

The machine is virus free (although it has previously been infected with Conficker and FTP.bat), and so I can't see what it would be that is causing it.

It seems to be a very clean shutdown, so it's not doing any harm, but it's been causing me such grief over the past couple of weeks.

This is what I found in Event Viewer.

GENERAL TAB:
The process C:\Windows\system32\shutdown.exe (**name**) has initiated the restart of computer **name** on behalf of user NT AUTHORITYNETWORK SERVICE for the following reason: No title for this reason could be found
 Reason Code: 0x800000ff
 Shutdown Type: restart

Check out MS' info about shutdowns here. There should be a file in the %windir%\system32\LogFiles\Shutdown\ directory with info about the shutdown, telling what's running at the time.

Whats recorded in the event log for the shutdown? It should record what requested the shutdown and from where.

I don't seem to have the %windir%\system32\LogFiles\Shutdown\ directory. Goes as far as LogFiles but there's no Shutdown folder in there.

The only thing I can see that requested the shutdown is NT AUTHORITY\SYSTEM from C:\Windows\system32\shutdown.exe or C:\Windows\SysWOW64\shutdown.exe.

Have you checked that you don't have some program scheduled in the task scheduler at about the time that the computer shuts down? If you do, change its scheduling and see if the shutdown time changes ...

Great to hear that you found the problem.

Rob is right. Please explain what it was that fixed it.
Many people come here looking for answers and only ask questions when they can't find their problem already answered. Explaining the fix will help others.

The previous infections I had removed had added a few randomly named jobs in my MS SQL installation, one of which was to call a reboot at that time every night.  Using SSMS I was able to find and remove these jobs, and I can confirm that the server didn't reboot last night.

Many thanks
