System.Data.OleDb.OleDbException: Not a valid password. in MS Access database ASP.NET/C# Web app -

I'm stucked within a brain-crunching problem. Developed an ASP.NET / C # web app with MS Access 2007 database. DB is in the same server (Windows Server 2008 R2), which I developed the app. It has a simple gridview to show search results when it runs on a local host then it works perfectly and is not giving any error. When it is deployed on the server in IIS, it starts giving the following error while searching the gridview.
