Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

I have written web service program to fetch all list names from web application, in that case I was getting access denied error while retrieving Title of SPWEB object.

Error:


at Microsoft.SharePoint.SPGlobal.HandleUnauthorizedAccessException(UnauthorizedAccessException ex) at 'SPWEB.Title' threw an exception of type 'System.UnauthorizedAccessException'

I have found that my current user don’t have access rights to access some of the sites, after giving required access rights my web service program gave me correct output without any errors.
