Reading Data Using Data Reader With Sql Server 2005 Conn

Hi
 
I have written a piece of code for Login form which reads the user id and password from db. It works fine with the Sql server 2000 but I get a error with Sql server 2005.
 
  SqlConnection conn = new SqlConnection("Data Source=D\SQLEXPRESS;Initial Catalog=model;Integrated Security=True");
        SqlCommand cmd = new SqlCommand("Select * from JsLoginDetails", conn);
        conn.Open();
        SqlDataReader dr = cmd.ExecuteReader();
        
          
        
        while (dr.Read())
        {
            if ((Login1.UserName == dr.GetValue(0).ToString()) && Login1.Password == dr.GetValue(1).ToString())
            {
                Response.Redirect("MainJs.aspx");
            }
            else
            {
                Login1.FailureText = "Invalid Userid Or Password";
            }
        }
        dr.Dispose();
        conn.Close();
    }
 
I get and error
Invalid object name 'JsLoginDetails'. 
 
pls help
