How to troubleshoot startup problems in Windows Server 2003
This article describes general procedures that you can use to troubleshoot startup problems in Windows Server 2003. A successful Windows startup includes of the following four phases: Initial phase Boot loader phase
Kernel phase & Logon phase
If a problem occurs during one of these phases, Windows may not start correctly, and you may experience one of the following problems: The computer stops responding (hangs). You receive an error message.If a startup problem occurs after you click Microsoft Windows Server 2003 on either the boot loader menu or when you receive the "Please select the operating system to start" message, files that the operating system needs may be missing or damaged. Windows provides a variety of options that you can use to troubleshoot this issue, including Safe mode, the Recovery Console, and an Automated System Recovery. How to Start the Computer by Using the Last Known Good ConfigurationIf the startup problem occurs immediately after you make a change to the computer (for example, after you install a new driver), try to start the computer by using the Last Known Good Configuration feature. When you use the Last Known Good Configuration feature, you start your computer by using the most recent settings that worked. This feature restores registry information and driver settings that were in effect the last time the computer started successfully. Use this feature when you cannot start Windows after you make a change to the computer (for example, after you install or upgrade a device driver). To start the computer by using Last Known Good Configuration, follow these steps: Click Start, and then click Shut Down. Click Restart, and then click OK. When you see the message Please select the operating system to start, press the F8 key. Use the arrow keys to select Last Known Good Configuration, and then press ENTER. Note NUM LOCK must be off before the arrow keys on the numeric keypad will function. If you are running other operating systems on the computer, click Microsoft Windows Server 2003 in the list, and then press ENTER.Notes By selecting Last Known Good Configuration, you can recover from problems such as a newly added driver that may be incorrect for your hardware. This feature does not solve problems caused by corrupted or missing drivers or files. When you select Last Known Good Configuration, only the information in registry key HKLM\System\CurrentControlSet is restored. Any changes you have made in other registry keys remain. If you can start your computer by using Last Known Good Configuration, the last change that you made to the computer (for example, the installation of a driver) may be the cause of the incorrect startup behavior. Microsoft recommends that you either remove or update the driver or program, and then test Windows for correct startup.
How to Start the Computer in Safe Mode
When you start the computer in Safe mode, Windows loads only the drivers and computer services that you need. You can use Safe mode when you have to identify and resolve problems that are caused by faulty drivers, programs, or services that start automatically. If the computer starts successfully in Safe mode but it does not start in normal mode, the computer may have a conflict with the hardware settings or the resources. There may be incompatibilities with programs, services, or drivers, or there may be registry damage. In Safe mode, you can disable or remove a program, service, or device driver that may prevent the computer from starting. To troubleshoot startup problems in Safe mode, follow these steps: Click Start, and then click Shut Down. Click Restart, and then click OK. When you see the message Please select the operating system to start, press F8. In Windows Advanced Option Menu, use the arrow keys to select Safe Mode, and then press ENTER.Note NUM LOCK must be off before the arrow keys on the numeric keypad will function. If you are running other operating systems on the computer, click Microsoft Windows Server 2003 on the list that is displayed, and then press ENTER. Do one of the following: If the computer does not start in Safe mode, try starting the computer by using the Recovery Console. If you still cannot start the computer, look for possible hardware problems, such as defective devices, installation problems, cabling problems, or connector problems. Remove any newly added hardware, and then restart the computer to see if the problem is resolved. If the computer starts in Safe mode, go to the next section to continue to troubleshoot the startup issue.To Use Event Viewer to Identify the Cause of the Startup ProblemView the event logs in Event Viewer for additional information that may help you to identify and diagnose the cause of the startup problem. To view events that are recorded in the event logs, follow these steps: Do one of the following: Click Start, point to Administrative Tools, and then click Event Viewer. Start the Event Viewer snap-in in Microsoft Management Console (MMC).In the console tree, expand Event Viewer, and then click the log that you want to view. For example, click System log or Application log. In the details pane, double-click the event that you want to view. To copy the details of the event, click Copy, open a new document in the program in which you want to paste the event (for example, Microsoft Word), and then click Paste on the Edit menu. To view the description of the previous event or the next event, press the UP ARROW key or the DOWN ARROW key.To Use System Information to Identify the Cause of the Startup ProblemThe System Information tool displays a comprehensive view of the computer's hardware, the system components, and the software environment. Use this tool to help identify possible problem devices and device conflicts. To do this, follow these steps: Click Start, and then click Run. In the Open box, type msinfo32, and then click OK. Look for problem devices or device conflicts. To do so: In the console tree, expand Components, and then click Problem Devices. Note any devices that are listed in the right pane. In the console tree, expand Hardware Resources, and then click Conflicts/Sharing. Note any resource conflicts that are listed in the right pane. If you identify a problem device, perform the appropriate action (for example, remove, disable, or reconfigure the device, or update the driver), and then restart the computer in normal mode. You can use Device Manager to remove or disable devices and their drivers. For more information about Device Manager, see the Use Device Manager to Identify the Cause of the Startup Problem section of this article. If the computer starts correctly, that particular device may be the cause of the startup problem. If you disabled a device to resolve the problem, make sure that the device is listed on the Windows Server 2003 Hardware Compatibility List (HCL), and that it is installed correctly. Also, contact the manufacturer to report the behavior and to obtain information about possible updates that can resolve the startup problem.For information about how to contact computer hardware manufacturers, click the appropriate article number in the following list to view the article in the Microsoft Knowledge Base: 65416 (http://support.microsoft.com/kb/65416/ ) Hardware and software vendor contact information, A-K60781 (http://support.microsoft.com/kb/60781/ ) Hardware and software vendor contact information, L-P60782 (http://support.microsoft.com/kb/60782/ ) Hardware and software vendor contact information, Q-ZMicrosoft provides third-party contact information to help you find technical support. This contact information may change without notice. Microsoft does not guarantee the accuracy of this third-party contact information.If no device conflicts or problem devices are reported by the System Information tool, look for programs that start automatically when Windows starts. To do so, follow these steps: In the console tree, expand Software Environment, and then click Startup Programs. Programs that start automatically when Windows starts are listed in the right pane. Disable the programs, and then restart the computer. For information about how to disable the program, see the program documentation or contact the manufacturer. If you disable the startup programs, and the startup problem is resolved, enable the programs again, one at a time. Shut down and restart the computer each time you enable a program, and note if the incorrect startup behavior occurs. If the behavior occurs, the last program that you enabled may be causing the incorrect startup behavior. To View the Safe Mode Boot Log FileTo troubleshoot startup issues, view the boot log file, Ntbtlog.txt, and then make a note of the drivers and services that did not load when you started your computer in Safe mode.This log file is located in the %SystemRoot% folder (by default, this is the Windows folder). The log file lists devices and services that load (and do not load) when you start the computer in Safe mode. You can use a text editor such as Notepad to open and view the log file. Use the list of drivers and services that did not load at startup to help identify the possible cause of the startup problem. Note Some startup problems may occur early in the startup process. In this scenario, Windows may not save the boot log file to the hard disk. To Use Device Manager to Identify the Cause of the Startup ProblemDevice Manager displays a graphical view of the hardware that is installed on your computer. Use this tool to resolve any possible device conflicts or to identify incompatible devices that may be the cause of the startup problem. To start Device Manager, follow these steps: Click Start, right-click My Computer, and then click Manage. Expand System Tools, and then click Device Manager. The devices that are installed on your computer are listed in the right pane. If a symbol is displayed next to a device, there may be a problem with the device. For example, a black exclamation point (!) on a yellow field indicates that the device is in a problem state. Note To disable a device in Device Manager, right-click the device, and then click Disable. Investigate possible device conflicts. To do so, double-click the device in the right pane, and then click the Resources tab. If a device conflict exists, it is listed under Conflicting device list. Note the Use automatic settings check box. If Windows successfully detects a device, this check box is selected, and the device functions correctly. However, if the resource settings are based on Basic Configuration n (where n is any number from 0 to 9), you may have to change the configuration. To do so, either click a different basic configuration from the list or manually change the resource settings. WARNING This procedure may require that you change the computer's complementary metal oxide semiconductor (CMOS) settings and the basic input/output system (BIOS) settings. Incorrect changes to the BIOS of the computer can result in serious problems. Change the computer's CMOS settings at your own risk. If Windows cannot resolve a resource conflict, verify that the computer is configured to permit Windows to enumerate the devices in the computer. To do so, enable the Plug and Play OS setting in the Setup tool of the computer's BIOS. To change the computer's BIOS settings, see the computer documentation or contact your computer manufacturer. If you identify a problem device, disable it, and then restart the computer in normal mode. If the computer starts correctly, the device that you disabled may be the cause of the startup problem. Make sure that the device is listed on the Windows Server 2003 Hardware Compatibility List (HCL) and that it is installed correctly. Also, contact the manufacturer to report the behavior and to obtain information about possible updates that can resolve the startup problem.For additional information about how to configure devices in Device Manager, click the following article number to view the article in the Microsoft Knowledge Base: 323423 (http://support.microsoft.com/kb/323423/ ) How to use Device Manager to configure devices in Windows Server 2003 How to Use System Configuration UtilitySystem Configuration Utility (Msconfig.exe) automates the routine troubleshooting steps that Microsoft Product Support Services technicians use when they diagnose Windows configuration issues. You can use this tool to modify the system configuration and troubleshoot the problem by using a process-of-elimination method.You must be logged on as Administrator or as a member of the administrative groups to use System Configuration Utility. If your computer is connected to a network, network policy settings may prevent you from using the utility. As a security "best practice," consider using the Run as command to perform these procedures.Note Microsoft strongly recommends that you do not use System Configuration Utility to modify the Boot.ini file on your computer without the help of a Microsoft support professional. Doing so may render your computer unusable.To Create a Clean Environment for TroubleshootingClick Start, click Run, type msconfig in the Open box, and then click OK. (To use the Run as command, type runas /user:administrator Path\msconfig.exe in the Open box, and then click OK. ) Click the General tab, click Diagnostic startup - load basic devices and services only, click OK, and then click Restart to restart your computer.

How to Use the Microsoft Windows Recovery ConsoleThe Recovery Console is a command-line tool that you can use to repair Windows if the computer does not start properly. You can start the Recovery Console from the Windows Server 2003 CD or at startup if the Recovery Console was previously installed to your computer.Use the Recovery Console if you used the Last Known Good Configuration startup option and it was not successful and you cannot start the computer in Safe mode. Microsoft recommends that you use the Recovery Console method only if you are an advanced user who can use basic commands to identify and locate problem drivers and files. To use Recovery Console, follow these steps: Insert the Windows Server 2003 installation CD in your CD-ROM or DVD-ROM drive, and then restart the computer. When you are prompted during text-mode setup, press R to start the Recovery Console.You can use the Recovery Console to: Access the drives on your computer. Enable or disable device drivers or services. Copy files from the Windows Server 2003 installation CD or copy files from other removable media. For example, you can copy a file that you need that was deleted. Create a new boot sector and a new master boot record (MBR). You might have to do this if there are problems starting from the existing boot sector.To Confirm That Your Hard Disk or File System Is Not DamagedTo confirm that your hard disk or file system is not damaged, start your computer from the Windows Server 2003 CD, start the Recovery Console, and then use the Chkdsk command-line utility. This may solve your problem.IMPORTANT Microsoft recommends that only advanced users or administrators use the Recovery Console. You have to know the password for the Administrator account to use the Recovery Console.For additional information about how to test and repair a damaged hard disk by using Chkdsk, see the "Using the Recovery Console and Using the Recovery Console Command Prompt" sections in the following article: 307654 (http://support.microsoft.com/kb/307654/ ) How to install and use the Recovery Console in Windows XP Note If Chkdsk reports that it cannot access your hard disk, you may have a hardware failure. Examine all cable connections and any jumper settings on your drive. Contact a computer repair professional, or the manufacturer of your computer for more assistance. If Chkdsk reports that it cannot fix all hard disk problems, your file system or MBR may be damaged or no longer accessible. Try using the appropriate Recovery Console commands, such as Fixmbr and Fixboot, contact a data recovery service, or repartition and then reformat your hard disk.WARNING: If you repartition and reformat your hard disk, you lose all information on the disk. IMPORTANT For more assistance, contact your computer manufacturer or a Microsoft Product Support Services professional. Only qualified personnel should try to repair your computer. If the computer repair is performed by non-qualified personnel, this may nullify your computer's warranty. For additional information about how to Use Recovery Console, click the following article numbers to view the articles in the Microsoft Knowledge Base: 326215 (http://support.microsoft.com/kb/326215/ ) How to use the Recovery Console on a Windows Server 2003-based computer that does not start How to Use Automated System Recovery To recover from a system failure by using Automated System Recovery (ASR), follow these steps: Make sure you have the following on hand before you start the recovery procedure: Your previously created ASR floppy disk. Your previously created backup media. The original operating system installation CD. If you have a mass storage controller and you are aware that the manufacturer has supplied a separate driver file for it (different from the driver files that are available on the Setup CD), obtain the file (on a floppy disk) before you start this procedure. Insert the original operating system installation CD into your CD-ROM or DVD-ROM drive. Restart your computer. If you are prompted to press a key to start the computer from CD, press the appropriate key. If you have a separate driver file as described in step 1, press the F6 key to use the driver as part of Setup when you are prompted. Press the F2 key when you are prompted at the start of the text-only mode section of Setup.You are prompted to insert the ASR floppy disk that you previously created. Follow the on-screen instructions. If you have a separate driver file as described in step 1, press F6 (a second time) when you are prompted after the system restarts. Follow the on-screen instructions. Notes ASR does not restore your data files. See Windows Help for more information about backing up and restoring your data files. If you are restoring a server cluster in which all nodes failed and the quorum disk cannot be restored from backup, use ASR on each node in the original cluster to restore the disk signatures and the partition layout of the cluster disks (quorum and nonquorum). For more information about backing up and restoring server clusters, see Windows Help. To Create an ASR Disk Set by Using Backup To use ASR, you must have an ASR disk set. To create an ASR disk set, follow these steps: Click Start, point to All Programs, point to Accessories, point to System Tools, and then click Backup. By default, the Backup or Restore Wizard starts, unless it is disabled. You can use the Backup or Restore Wizard to create an ASR disk set by answering All information on this computer in the What do you want to backup? section. Otherwise, you can go to the next step to create an ASR disk set in Advanced Mode. Click the Advanced Mode link in the Backup or Restore Wizard. On the Tools menu, click ASR Wizard. Follow the instructions that appear on your screen. Notes You need a blank 1.44 megabyte (MB) floppy disk to save your system settings and media to contain the backup files. If your computer does not have a floppy disk drive, perform an ASR backup on the computer without the floppy disk drive. Copy the Asr.sif and Asrpnp.sif files that are located in the %SystemRoot%\Repair folder to another computer with a floppy disk drive, and then copy those files to a floppy disk. To perform this procedure, you must be a member of the Administrators or Backup Operators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure. As a security "best practice," consider using the Run as command to perform this procedure. This procedure backs up only those system files that you must have to start your system. You must back up your data files separately. After you create the ASR set, label this floppy disk and the backup media carefully and keep them together. To use the backup media, you must have the floppy disk that you created with that set of media. You cannot use a floppy disk that you created at a different time or with a different set of media. You must also have your Setup CD available at the time you perform ASR. Keep the ASR set in a secure location. The ASR set contains information about your systems configuration that might be used to cause damage to your system. If you are backing up a server cluster, run the Automated System Recovery Wizard on all nodes of the cluster, and make sure that the Cluster service is running when you start each ASR backup. Make sure that one of the nodes on which you run the Automated System Recovery Preparation Wizard is listed as the owner of the quorum resource while the wizard is running. How to Repair Your Installation of WindowsYou may be able to repair a damaged Windows Server 2003 installation by running Windows Setup from the Windows CD.To repair your installation of Windows, follow these steps: Insert the Windows Server 2003 CD in the CD-ROM or DVD-ROM drive. If the Windows CD displays the What would you like to do? menu, click Exit. Turn off your computer, wait ten seconds, and then turn your computer back on. If you are prompted to start your computer from the CD, do so.Note You must be able to start your computer from the Windows Server 2003 CD-ROM to run Windows Setup.
