    Thanks all! The issues was there because SQL Server 2008 Native Client was not installed on the machine. We had installed only required software the production machine. It did not have SQL Management Studio installed on the server and so the native client.

    After reading various blogs, I could figure out it could be sql native client issue.

    Thanks all again. I appreciate your time. Smile
