If you are searching the internet for this error you may find a lot of solutions like:

• This technet article 
• Or inside "Search Administration" page under "Shortcuts" open the links "Add new link" and "Manage links" without changing or adding something

And then rerun the Health Analyzer rule.

Sounds really good because this solution does not require special knowledge or changes in SharePoint Farm ... and the TRUTH is that we may need to repeat the aforementioned steps several times until the message disappear ...  YES it is really working in this way.

Enjoy and happy SharePointing...
