Inventory Scanner error 021

Hello NG

On Consoleone on the Workstation Scan Log I can see, that a lot of
workstation are present with the following error: Message: 021: Unable to
access the Custom Scan file.

In the Knowledgebase I found the following action to do, but it didn`t solve
the problem

Action: In ConsoleOne, run the Custom Scan Editor. The editor will validate
the Custom Scan file.

Action: Since the custom scan file is a stream file in NDS, verify the
validity of the streams with DSrepair on every server that holds a copy of
the partition where the workstation policy exists. Also, recreate the custom
scan file as corruption could have happened during creation.

Where could be here the problem?

Thanks in advance for your help.
