I am using Visual Studio 2012 Ultimate , MySql Database , MySQL ODBC 5.1 Driver
I have created a user DSN from Administrative tool in Control Panel (same on both my development PC and Server computer i-e Windows Server 2008)
I have deployed web application from my PC to Server using IIS 7.0 and when i access it from remote computer through,then crystal report asks for login parameters and don't accept crdentials.
i am using the following code.

    string databaseName = "hr";
    string serverName = "";
    string userID = "userID";
    string pass = "password";
protected void btn_search_Click(object sender, EventArgs e)
        CrystalReportViewer1.Visible = true;
         ReportDocument reportDocument = new ReportDocument();
        string reportPath = Server.MapPath(@"~/GeneralEmpReports/test.rpt");

        reportDocument.SetDatabaseLogon(userID, pass, serverName, databaseName);
        reportDocument.SetParameterValue("D", tbx_ddoCode.Text.ToUpper());
        CrystalReportViewer1.ReportSource = reportDocument;
