After renamed the drive SharePoint Server 2010 working well but when you go in Search service and click on Content sources we are getting below error.

Unable to cast COM object of type 'Microsoft.Office.Server.Search.Administration.MSSITLB.CGatheringManagerClass' to interface type 'Microsoft.Office.Server.Search.Administration.MSSITLB.IGatherManagerAdmin3'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{0FF1CE14-013A-0000-0000-000000000000}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).

Hi Giri, When you say you renamed the drive sharepoint server 2010, do you mean the physical hard drive sharepoint 2010 is installed on?

If not can you explain a little more the steps you did?
