SUMMARY

This article describes how to enable Distributed File System (DFS) debugging in Windows 2000. This method uses the checked version of the Netapi32.dll file in conjunction with a registry entry to output DFS API debug statements to a debugger.

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, you should also update your Emergency Repair Disk (ERD).

To Enable Debug Output

1. Rename the original Netapi32.dll file in the %SystemRoot%\System32 folder to another name (such as Netapi32.dll.orig). Note that this file is normally in use by the system and must be replaced while the server is offline.



2. Copy the checked Netapi32.dll file to the %SystemRoot%\System32 folder. The checked file should match the build and service pack revision of the existing file.



3. Add or set the NetAPIDfsDebug (REG_DWORD) entry in the registry under HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\DFS. Set the data value to 0x1.



4. Restart the computer.

To Disable Debug Output

1. Set the NetAPIDfsDebug entry in the registry to 0x0, remove the entry, or replace the checked Netapi32.dll file with the original.



2. Rebstart the computer.
