Login failed for user 'someone' - sql-server

Question

I work on Microsoft SQL Server 2008 R1 and visual studio 2010.
My target is to clone a server to a new machine. However, after setting the application up and entering "local/storytelling" in the browser's URL, the error msg appears. After google the possible mistake, I have set the authentication mode form "Windows Authentication mode" to "SQL Server and Windows Authentication mode".
But the error remains... And I have no more idea now.
Here is the error msg:
[SqlException (0x80131904): Login failed for user 'storytelling'.]

I don't know what's the problem to the code:(Source file: "Default.aspx.vb")

Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim conn As New SqlConnection(ConfigurationManager.ConnectionStrings("StoryTelling2ConnectionString").ConnectionString)
Dim cmmd As New SqlCommand
Dim strSQL As String
conn.Open()
The error log highlight conn.Open() in red color. I guess it's probably I lost some steps as I cloned the server. But I have no idea what steps I ignored.
Please provide some suggestion.
Thanks.

I finally know what happened. Sorry for the poor representation of my problem. I take reference to this and this, finding out that the windows server 2008 has installed an SQL Express edition for me. Nevertheless, I don't know at all, so I install another SQL Server. In this condition. I have two SQL server edition, and according to the thread MSDN FORUM, the log in to the different server is quite different in the "Server Name" input.
In short, my connection string is always incompatible with the "Server Name" input, and thus the log in process always failed.
