crystal Report的Logon Fail问题

我在web form里面嵌入的crystalReportViewer，页面调用的时候，报错说登录错误。
错误如下Logon failed.

我查了ms说cr在sql2k下有这样的logon fail的bug,但是，根据她的方法修改，还是
没有效果，一样的logon fail.
我的代码如下
public class test4 : System.Web.UI.Page
{
protected CrystalDecisions.Web.CrystalReportViewer CrystalReportViewer1;

//Crystal Report Variables
SalesStatistics crReportDocument=new SalesStatistics();

//'CrystalReport1' must be the name the CrystalReport
TableLogOnInfo crTableLogOnInfo = new TableLogOnInfo();
ConnectionInfo crConnectionInfo = new ConnectionInfo();

//Crystal Report Properties
CrystalDecisions.CrystalReports.Engine.Database crDatabase;
CrystalDecisions.CrystalReports.Engine.Tables crTables;
CrystalDecisions.CrystalReports.Engine.Table crTable;

private void Page_Load(object sender, System.EventArgs e)
{
crConnectionInfo.ServerName = "(local)";
crConnectionInfo.DatabaseName = "databasename
crConnectionInfo.UserID = "userid
crConnectionInfo.Password = "password
crDatabase = crReportDocument.Database;
crTables = crDatabase.Tables;

foreach(CrystalDecisions.CrystalReports.Engine.Table crTable in crTables)
{

crTableLogOnInfo = crTable.LogOnInfo;
crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
crTable.ApplyLogOnInfo(crTableLogOnInfo);
}

CrystalReportViewer1.ReportSource = crReportDocument;




}

我现在在前端的aspx页面里面，直接使用绑定的dataset方式，
然后设置crystalReport对象的setDataSource()方法，指定前面绑定的
数据集可以成功打开CrystalReportViewer,
但是，通过我的上一贴的代码，指定crTable.ApplyLogOnInfo(crTableLogOnInfo);方法，
还是产生Logon Fail错误。

没人愿意回答，那就谁来接分。
