JSI Tip 0592 - Error adding NetBEUI - Registry Service Subkey already exists.

The subject problem is generally caused by registry corruption, perhaps as a result of a failed install. To correct the problem:

1. Run Rdisk /S to backup the registry.

2. Delete the following registry keys using Regedt32 (You may need to alter the key permissions - Security / Permissions):

HKEY_LOCAL_MACHINE\SYSTEM\CCS\Services\NBF

HKEY_LOCAL_MACHINE\System\CCS\Enum\Root\Legacy_NBF

3. Shutdown and restart.

4. Install NetBEUI.
