HOW TO: Use Ntdetect.chk to Identify Hardware Problems in Windows 2000 (320040)

SUMMARY

This step-by-step article describes how to use the debug version of Ntdetect.com (Ntdetect.chk) to help you to identify hardware problems that may prevent your computer from starting.

If you are experiencing problems starting your computer because of a hardware problem, you can use Ntdetect.chk to determine the hardware component that may be causing the problem. Ntdetect.chk is located in the Debug.cab file from the Windows 2000 Resource Kit companion compact disc (CD). Open the Debug.cab file, and then extract the Ntdetect.chk file.

How to Use Ntdetect.chk to Identify Hardware Problems

This section describes two methods that you can use to identify hardware problems.

Method 1: Use Ntdetect.chk to Start the Computer from the Windows 2000 Setup Boot Disks

1. Create a duplicate copy of Setup disk 1 from the Windows 2000 Setup boot disks.For additional information about how to create startup disks for Windows 2000, click the article number below to view the article in the Microsoft Knowledge Base:

2. Rename the Ntdetect.com file on the copy of the Windows 2000 Setup boot disk that you created in step 1 to "Ntdetect.bak."
3. Extract the Ntdetect.chk file from the Debug.cab file on the Windows 2000 Resource Kit CD to the Windows 2000 Setup boot disk.
4. Rename the Ntdetect.chk file on the copy of the Windows 2000 Setup boot disk to "Ntdetect.com."
5. Insert the copy of the Windows 2000 Setup disk that you created in step 1 in drive A, and then restart the computer.

Method 2: Use Ntdetect.chk to Start the Computer from the Hard Disk

If you do not want to use the Windows 2000 Setup boot disk, use the following procedure to replace the Ntdetect.com in the root folder of your system partition.

NOTE: Depending on the current state of your computer, you may have to start the computer in safe mode or use the Windows Recovery Console to perform the procedure that is described in this section.

You can use the Recovery Console to help recover a Windows-based computer that either does not start properly or does not start at all. If safe mode and other startup procedures do not work, you may want to use the Recovery Console. Microsoft recommends this method only if you are an advanced user who can use basic commands to identify and locate problem drivers and files. Additionally, you must be an administrator to use the Recovery Console. For additional information about how to start Windows in safe mode, click the article number below to view the article in the Microsoft Knowledge Base: To use Ntdetect.chk to start the computer from the hard disk:

1. Rename Ntdetect.com to "Ntdetect.bak" in the root folder of your system partition.
2. Extract the Ntdetect.chk file from Debug.cab file in the Windows 2000 Resource Kit CD-ROM to the root of your system partition.
3. Rename Ntdetect.chk to "Ntdetect.com" in the root folder of your system partition, and then restart the computer.
