Hello, I have a new Fujitsu Siemens computer with Windows server 2003 installed on it. The system shuts down automatically every night at 12am. This is what the Event Viewer shows every time: (e.g. 7/30/06 at 12:00:12 AM with source User32) The process winlogon.exe has initiated the power off of computer 2SERVE on behalf of user 2C\Administrator for the following reason: No title for this reason could be found Reason Code: 0x0 Shutdown Type: power off Comment: The computer is connected to a UPS. The power scheme is set to Always On. There are no scheduled tasks listed other than backups. Can anybody help? Thanks in advance.

Check the backup settings. One of the settings, depending on software, is shut the server down after backup. Unload your UPS software for one night to see if the shutdown stops. I have had UPS software shut the system down due to faulting com port communication. Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

I am using ntbackup for the moment, and there are no options to shut the system down after the backup. The computer does not have UPS software, the power cable is just plugged into a UPS unit. This morning a dialog window mentioned that the system wanted to shut down but didn't because an application needed user interaction - a .txt file was still open and not saved.

The default Windows UPS service is stopped because the UPS unit cannot be controlled by the server - there is no (usb-)connection.

OK so that takes out backup and ups. I don't know of any system function that will shut the system down on a regular schedule if you don't see it scheduled in scheduler. What applications are you running on the server? Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

I made a list of all running processes using hijackthis: Running processes: C:\WINDOWS\System32\smss.exe C:\WINDOWS\system32\winlogon.exe C:\WINDOWS\system32\services.exe C:\WINDOWS\system32\lsass.exe C:\WINDOWS\system32\svchost.exe C:\WINDOWS\System32\svchost.exe C:\WINDOWS\system32\spoolsv.exe C:\WINDOWS\system32\serverappliance\appmgr.exe C:\Program Files\ASCOMP Software\BackUp Maker\Add-Ons\RunAsService\daemon.exe C:\WINDOWS\system32\Dfssvc.exe C:\WINDOWS\System32\dns.exe C:\WINDOWS\system32\serverappliance\elementmgr.exe C:\WINDOWS\System32\svchost.exe C:\WINDOWS\system32\inetsrv\inetinfo.exe C:\WINDOWS\System32\ismserv.exe C:\Program Files\ASCOMP Software\BackUp Maker\Add-Ons\RunAsService\nmsaccess.exe C:\WINDOWS\system32\ntfrs.exe C:\Program Files\ASCOMP Software\BackUp Maker\bkmaker.exe C:\WINDOWS\system32\serverappliance\srvcsurg.exe C:\Program Files\RealVNC\VNC4\WinVNC4.exe C:\WINDOWS\system32\tcpsvcs.exe C:\Program Files\Exchsrvr\bin\exmgmt.exe C:\Program Files\Exchsrvr\bin\mad.exe C:\Program Files\Common Files\System\MSSearch\Bin\mssearch.exe C:\WINDOWS\System32\svchost.exe C:\Program Files\Exchsrvr\bin\store.exe C:\Program Files\Exchsrvr\bin\emsmta.exe C:\WINDOWS\System32\svchost.exe C:\WINDOWS\Explorer.exe C:\WINDOWS\System32\svchost.exe C:\WINDOWS\system32\NOTEPAD.exe C:\WINDOWS\system32\NOTEPAD.exe c:\windows\system32\inetsrv\w3wp.exe C:\Program Files\Hijack This\hijackthis.exe R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Default_Page_URL = res://shdoclc.dll/softAdmin.htm R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = res://shdoclc.dll/softAdmin.htm O4 - HKLM\..\Run: [ISUSPM Startup] C:\PROGRA~1\COMMON~1\INSTAL~1\UPDATE~1\ISUSPM.exe -startup O4 - HKLM\..\Run: [ISUSScheduler] "C:\Program Files\Common Files\InstallShield\UpdateService\issch.exe" -start O4 - HKLM\..\Run: [ExclusiveFiles] "C:\Program Files\ASCOMP Software\BackUp Maker\Add-Ons\ExclusiveFiles\fileAccessManager.exe" O4 - HKLM\..\Run: [UserFaultCheck] %systemroot%\system32\dumprep 0 -u O4 - Global Startup: PlexTools Professional.lnk = C:\Program Files\Plextor\PlexTool.exe O16 - DPF: {6414512B-B978-451D-A0D8-FCFDF33E833C} (WUWebControl Class) - http://update.microsoft.com/windowsupdate/v6/V5Controls/en/x86/client/wuweb_site.cab?1153436851158 O17 - HKLM\System\CCS\Services\Tcpip\Parameters: Domain = 2c.local O17 - HKLM\Software\..\Telephony: DomainName = 2c.local O17 - HKLM\System\CCS\Services\Tcpip\..\{0540710B-F03B-4E09-A4AF-DEE4E43BB477}: NameServer = 192.168.1.100 O17 - HKLM\System\CS1\Services\Tcpip\Parameters: Domain = 2c.local O17 - HKLM\System\CS1\Services\Tcpip\..\{0540710B-F03B-4E09-A4AF-DEE4E43BB477}: NameServer = 192.168.1.100 O20 - Winlogon Notify: dimsntfy - C:\WINDOWS\SYSTEM32\dimsntfy.dll O23 - Service: BackUpMaker - ASCOMP Software GmbH - C:\Program Files\ASCOMP Software\BackUp Maker\Add-Ons\RunAsService\daemon.exe O23 - Service: NMSAccess - Unknown owner - C:\Program Files\ASCOMP Software\BackUp Maker\Add-Ons\RunAsService\nmsaccess.exe O23 - Service: VNC Server Version 4 (WinVNC4) - Unknown owner - C:\Program Files\RealVNC\VNC4\WinVNC4.exe" -service (file missing) I hope you can identify anything that can cause the shutdown.

check if its progammed to do that via Scheduled Tasks
