Safe next steps
- For 15014 (ERROR_EVT_FILTER_ALREADYSCOPED), record the event channel, provider, query or subscription and the exact operation that returned this code.
- Use Event Viewer or the responsible application’s logs to confirm whether the channel, event publisher or subscription exists and is accessible.
- Do not delete event logs or change audit policy merely to clear a return code.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
