SharePoint 2010: Search Service is not able to connect to the machine that hosts the administration component

Had a strange Search error in a new SharePoint 2010 farm:

The search service is not able to connect to the machine that hosts the administration component. Verify that the administration component 'bae8d161-c132-4570-aa0d-57baf6cf9d9b' in search application 'Search Service Application 1' is in a good state and try again."

I was unable to start any crawls as a result.

The search services were all started correctly but in the Application Services window it showed “Error”. The fix for me was to click on the Search Service Application name in the list of Application Services, choose Properties on the ribbon above, and change the Application Pool to another one (in my case, from SharePoint Web Services Default app pool to SharePoint Web Services System).

Hope it helps someone.
