Crystal Reports not printing

[skrishnan68]

Hello,
When printing a crystal report from my VB.NET application, it only
prints a blank page. The report was created in Crystal Enterprise
v10.0. Recently we upgraded our servers and changed the OS to Windows
2003 and IIS 6.0. That is when the issue started. I am able to see
the report on the screen. However, when I click on the print icon and
select the printer from the printer dialog box, I get a blank page.
When the website was running on a Windows 2000/IIS 5.0 server, I never
had this problem and I am not sure what the issue is. Here is the
piece of code I am using to display the report

Dim rptReport As HSCertificate 'Report class
Dim myTable As CrystalDecisions.CrystalReports.Engine.Table
Dim myLogin As CrystalDecisions.Shared.TableLogOnInfo
Dim paramFields As New ParameterFields
Dim paramField As New ParameterField
Dim Discreteval As New ParameterDiscreteValue
Dim strStatus As String

strStatus = CheckStatus(context.User.Identity.Name)
If Not strStatus = "Pass" Then
Response.Redirect(strStatus)
End If

rptReport = New HSCertificate
For Each myTable In rptReport.Database.Tables
myLogin = myTable.LogOnInfo

myLogin.ConnectionInfo.Password = "myP@55w0rd"

myLogin.ConnectionInfo.UserID = "guestuser"

myLogin.ConnectionInfo.ServerName = "localhost"

myTable.ApplyLogOnInfo(myLogin)
Next

rptReport.PrintOptions.PaperOrientation =
PaperOrientation.Landscape

rptReport.Refresh()

paramField.ParameterFieldName = "@login"
Discreteval.Value = context.User.Identity.Name
paramField.CurrentValues.Add(Discreteval)
paramFields.Add(paramField)
Me.CrystalReportViewer1.ParameterFieldInfo = paramFields
Me.CrystalReportViewer1.ReportSource = rptReport

rptReport.Refresh()

The report is a test report and displays only the company logo and the
developer name.
Can anyone point what could be the issue.
Thank you
SK
