Sharepoint Search Crawl error (Error HRESULT E_FAIL has been returned from a call to a COM component)

SharePoint search was throwing error very next morning when trying to search anything on the page or were trying to crawl the url's. After looking at the Logs and EV, it was throwing the following error.

Error:-

HRESULT E_FAIL has been returned from a call to a COM component. Troubleshoot issues with Microsoft SharePoint Foundation.

Resolution:-

1) Go to Windows services

2) Click SharePoint Search Service and open properties.

3) Put in the correct new password and restart the service again


It should be good to go now. Reason was that after changing the password in the SP farm, password was not changed under services and that's why was throwing this weird error.
