Error: 9999 Mismatch in Service Account Username when Attempting to Rotate Service Password

Symptom

When you scan an endpoint, the scan does not complete, and the following error occurs:

9999 Mismatch in service account username when attempting to rotate service password

Cause

The error is caused by the Local Admin Password TTL Days setting. This setting belongs to a legacy feature that rotated local account passwords. The product no longer supports this feature, and the setting is 0 by default in current installations and upgrades.

Resolution

1. Set Local Admin Password TTL Days to 0 for the affected service.
2. Restart the service from the UI.
