IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY
There is a compatibility issue between the Imagehlp.dll file in Windows 2000 and the debug tools in earlier versions of Windows NT. This article describes how to use the Windows NT 4.0 debug files in Windows 2000.

MORE INFORMATION
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys and Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).

To use the Windows NT 4.0 kernel-mode debug tools (I386kd.exe and Alphakd.exe) in Windows 2000, you must remove the Imagehlp.dll file from the list of known dynamic link library (DLL) files in the registry. This forces the debug tools to use their own version-specific copy of the Imagehlp.dll file, which resolves the compatibility issues.

To use the Windows NT 4.0 debug files in Windows 2000, use the following steps:


 * 1) Start Registry Editor (Regedt32.exe).
 * 2) Locate the Imagehlp value under the following registry key:
 * 3) On the Edit menu, click Delete, and then click Yes.
 * 4) Locate the ExcludeFromKnownDlls value under the following registry key:
 * 5) On the Edit menu, click Multi String, type imagehlp.dll, and then click OK.
 * 6) Quit Registry Editor, and then restart the computer.
