SUMMARY
This article describes general procedures that you can use to troubleshoot shutdown problems in Microsoft Windows 2000.
When Windows 2000 shuts down, messages are sent to the devices, system services, and programs that are installed on the computer to notify them that Windows is preparing to shut down. The operating system waits for responses from programs that are running to make sure that the programs save unsaved data to the hard disk and shut down properly. Each device, service, and program that is running usually responds to the shutdown message with a message that states the program can be closed.
You may experience one or more of the following symptoms when you try to shut down the computer:
- The computer stops responding (hangs). When this symptom occurs, a teal or black screen may be displayed.
- The computer does not turn off when you receive the "It is now safe to turn off your computer" message.
- An error message is displayed on the screen.
Typical causes of shutdown problems include the following problems:
- Faulty or incompatible device drivers.
- System services that either do not respond correctly or send busy request messages to the system.
- Faulty or incompatible programs.
How to Troubleshoot Shutdown Problems in Windows 2000
To troubleshoot shutdown problems and to isolate the cause of the incorrect shutdown behavior, use the following methods:
- Use Task Manager to identify the cause of the shutdown behavior.
- Undo any recent changes to the computer.
- Use safe mode to identify the cause of the shutdown behavior.
- Confirm that the computer's complementary metal oxide semiconductor (CMOS) and basic input/output system (BIOS) settings are correct.
How to Use Task Manager to Identify the Cause of the Shutdown Behavior
Use Task Manager to determine the programs that are currently running on the computer. For each program that is listed in Task Manager, manually quit the program, and then shut down and restart the computer to test if the shutdown problem is resolved. To do this, follow the procedure that is described in this section.
NOTE: All programs that are currently running on the computer may not be listed in the Applications tab of Task Manager.
- Press CTRL+ALT+DELETE, and then click Task Manager.
- Click the Applications tab.
- In the Task column, click the program that you want to quit, and then click End Task.
- Quit Task Manager.
- Shut down the computer.
How to Undo Any Recent Changes to the Computer
If the shutdown behavior occurs immediately after you make a change to the computer (for example, you install or upgrade either a program, a service, or hardware that has device drivers), undo the last change that you made. For example, remove either the last driver or the last program that you installed, and then shut down and restart the computer to test if the computer shuts down correctly.

How to Use Safe Mode to Identify the Cause of the Shutdown Behavior
When you start your computer in safe mode, only a minimal set of essential drivers and services is loaded. Safe mode is a useful diagnostic tool to use when you want to identify and resolve problems that are caused by faulty drivers, programs, or services that start automatically.
To determine if the computer shuts down correctly in safe mode:
- Restart the computer.
- When you receive the "Please select the operating system to start" message, press F8.
- On Windows Advanced Option Menu, use the arrow keys to select Safe Mode, and then press ENTER.
- If you are using a dual-boot or multiple-boot computer, select Microsoft Windows 2000 from the list that is displayed, and then press ENTER.
- After the computer starts in safe mode, shut down the computer.
If the computer shuts down correctly when it is in safe mode, repeat steps 1 through 4 to restart the computer in safe mode, and then go to step 6 and follow the remaining steps of this procedure to troubleshoot and identify the cause of the shutdown problem. - View the boot log file, Ntbtlog.txt, and then make a note of the devices and services that did not load when you started your computer in safe mode.
The Ntbtlog.txt file is located in the %SystemRoot% folder (by default, this is the Winnt folder). You can use Microsoft Notepad to open and view the file. The Ntbtlog.txt file lists devices and services that load (and do not load) when you start your computer in safe mode.
NOTE: If there are third-party drivers or services that run when your computer is in normal mode but do not run when your computer is in safe mode, the third-party drivers or services may be the cause of the incorrect shutdown behavior. - Restart the computer in normal mode, and then either remove the drivers for each of the drivers and services that you identified in the Ntbtlog.txt file to be possible causes of the incorrect shutdown behavior or stop or disable the services one at a time.
You can use Device Manager to remove or disable devices and their drivers.For additional information about how to manage devices by using Device Manager, click the article numbers below to view the articles in the Microsoft Knowledge Base:199276 How to Manage Devices in Windows

- Shut down the computer to test if the shutdown problem is resolved.
- After you identify the problem service or driver, either reinstall the service or the driver if you suspect that a file is damaged or contact the manufacturer to report the behavior and to obtain information about possible updates that you can use to resolve the shutdown behavior.
How to Confirm that the Computer's CMOS/BIOS Settings Are Correct
Warning This procedure may involve changing your computer's CMOS settings and altering the BIOS. Incorrect changes to the BIOS of your computer can result in serious problems. Change the computer's CMOS settings at your own risk.
Incorrect or damaged CMOS and BIOS settings can cause startup and shutdown problems. For information about the correct CMOS and BIOS settings for your computer and how to check and change these settings, refer to the computer documentation or contact the manufacturer of your computer. To confirm that the computer's BIOS is current, contact the computer manufacturer to inquire about the latest BIOS update available for your computer.

How to Use a Parallel Installation to Identify the Cause of the Shutdown Behavior
To use a parallel installation to troubleshoot shutdown behavior:
- Install a new copy of Windows 2000 to a separate partition on the computer (create a parallel installation), and then install drivers and programs one at a time on the parallel installation.
- Shut down and restart the computer between each program installation and note if the incorrect shutdown behavior occurs.
If the behavior occurs, the last driver or the program that you installed may be the cause of the incorrect shutdown behavior.
- Either remove or update the driver or the program from the original installation, and then test Windows for proper shutdown.
If the problem is resolved, remove the parallel Windows installation.
