Servername changed, but Login failed

Question

CR2008 full version, VS 2005 Standard (did not come with CR).  Everything works great on dev box, but cannot login to sql server 2000 when I deploy to client site.  I have updated both VS and CR to their latest service packs.  Deployed using the redist instead of merge modules.  Installation went fine.  Application can Read and Update sql data, but when I open the report, it waits a while, then brings up a logon screen.  I added a VerifyDatabase() which replaced the logon screen with this error message:
CrystalDecisions.CrystalReports.Engine.LogOnException: Log on failed...
I'm not changing anything other than the ServerName.  DatabaseName is the same and it's integrated security, so no UserID/Password.  I can't test it on the server because the server is SBS 2000, which CR2008 runtime apparently will not install on.
I went through Mike's Thread (*** Canu2019t Change ServerName or DatabaseName At Runtime In Crystal Report!!!) which I thought would do it, but it didn't.
I'll post my code below.  Note the MessageBox output at the end shows me the correct servername, databasename, and true (integrated security).
ReportDocument crptdocGradeSheet = new ReportDocument();
crptdocGradeSheet.Load(Application.StartupPath + "\\Reports\\GradeSheet.rpt");
TableLogOnInfo crTableLogOnInfo = new TableLogOnInfo();
foreach (Table crTable in crptdocGradeSheet.Database.Tables)
                crTableLogOnInfo = crTable.LogOnInfo;
                crTableLogOnInfo.ConnectionInfo.ServerName = Program.conn.DataSource.ToUpper();
                crTableLogOnInfo.ConnectionInfo.IntegratedSecurity = true;
                crTable.ApplyLogOnInfo(crTableLogOnInfo);
crptdocGradeSheet.VerifyDatabase();
crptdocGradeSheet.SetParameterValue("@ClassKEY", _ClassKEY);
crptdocGradeSheet.SetParameterValue("ClassName", _ClassName);
crptdocGradeSheet.SetParameterValue("InstructorName", _InstructorName);
this.crvGradeSheet.ReportSource = crptdocGradeSheet;
this.crvGradeSheet.Refresh();
            MessageBox.Show(crptdocGradeSheet.Database.Tables[0].LogOnInfo.ConnectionInfo.ServerName.ToString() + "\r\n" + crptdocGradeSheet.Database.Tables[0].LogOnInfo.ConnectionInfo.DatabaseName.ToString() + "\r\n" + crptdocGradeSheet.Database.Tables[0].LogOnInfo.ConnectionInfo.IntegratedSecurity.ToString());
            MessageBox.Show(crvGradeSheet.LogOnInfo[0].ConnectionInfo.ServerName.ToString() + "\r\n" + crvGradeSheet.LogOnInfo[0].ConnectionInfo.DatabaseName.ToString() + "\r\n" + crvGradeSheet.LogOnInfo[0].ConnectionInfo.IntegratedSecurity.ToString());
What am I doing wrong?

How do you implement Single Sign On (SSO) using Crystal Reports XI in a Visual Studio .NET web application?
Resolution
====================
NOTE:
This article applies to Crystal Reports XI, Crystal Reports XI Release 2, and Crystal Reports for Visual Studio .NET 2005. The solution will not work in Crystal Reports 10 or lower.
====================
There are two steps to implementing Single Sign On (SSO) using Crystal Reports XI in a Visual Studio .NET web application. The first step has several sub-steps that are outlined in the referenced article.
The required system configuration is explained in a Microsoft white paper. Search for "Troubleshooting_Kerberos_Delegation" at www.microsoft.com.
Within your Visual Studio .NET code, you will need to add code between the section in which report objects are set and the section in which the log on code is set ('if .IntergatedSecurity = False'). The code to add is:
Report.DataSourceConnections(0).IntegratedSecurity = True
