I've have been using EO.PDF successfully on my development web server for some time. Details:
Microsoft Windows Server 2008 R2 Standard IIS 7.5
I have just published by ASP.NET web application to a production server:
Microsoft Windows Server 2003 Standard Edition Server Pack 2 IIS 6.0
The web application is set up to use Windows Authentication enabled and all other authentication methods disabled.
The Web Page conversion works perfectly on the development web server but on the production web server I get the error:
EO.Pdf.HtmlToPdfException: Failed to convert Url 'http://myproductionserver/scorecard/Scores/Scores.aspx?SupplierCode=9495&PeriodFrom=201304&PeriodTo=201306&PDF=True'.(1102:This is not a valid HTML document.) at EO.Pdf.Internal.de.a(String A_0, Boolean A_1) at EO.Pdf.Internal.de.b(HtmlToPdfOptions A_0, String A_1, Boolean A_2) at EO.Pdf.Internal.de.a(bs A_0) at EO.Pdf.Internal.lr.c.a(Byte[] A_0)
When I configure the production server to use Anonymous Access the conversion to PDF works without error.
However I don't want Anonymous Access on the production webserver web application, the application needs to validate the windows user. Is there something in the setup/config files that IIS 6 requires that IIS 7.5 does not require to enable EO.Pdf to work with only with Windows Authentication.
I'm using EO.Pdf.dll File version 5.0.22.2. (2013)
Thanks.

Hi,
EO.Pdf uses the calling thread's user context to authenticate with the server. So for example, if you run EO.Pdf interactively, then the current logged in user will be used to authenticate with the server. If you run EO.Pdf inside IIS, then the IIS user context will be used to authenticate with the server. You will want to check the calling thread's user context and see if that user has sufficient permission to authenticate with your server. As long as the calling thread's user context has sufficient permission, it should work.
Thanks!

Hi
The issue is that the application works fine with Windows Authentication enabled on Microsoft Windows Server 2008 R2 Standard IIS 7.5 but not on Microsoft Windows Server 2003 Standard Edition Server Pack 2 IIS 6.0
Can you be a little more clearer why there should be the error when the code to generate the PDF is the same?
Is there a set up issue for Microsoft Windows Server 2003 Standard Edition Server Pack 2 IIS 6.0 that I'm missing to ensure the PDF generation works.
Thanks

Hi,
We are not expert on IIS or Windows administration, so you may want to consult your server administrator on that. From our product point of view, the user context of the calling thread is all that matters.
Thanks!

ASP.NET C# Code extract:
sUser = System.Threading.Thread.CurrentPrincipal.Identity.Name;
String thisPage = HttpContext.Current.Request.Url.AbsoluteUri+"&PDF=True"; PdfDocument docPDF = new PdfDocument(); ; HtmlToPdf.ConvertUrl(thisPage, docPDF);
docPDF.Save(pdfName);
The value of sUser is a valid domain user, the windows log on user. Is this calling thread's user context you refer? In this case can you further look into the error reported:
EO.Pdf.HtmlToPdfException: Failed to convert Url 'http://myproductionserver/scorecard/Scores/Scores.aspx?SupplierCode=9495&PeriodFrom=201304&PeriodTo=201306&PDF=True'.(1102:This is not a valid HTML document.) at EO.Pdf.Internal.de.a(String A_0, Boolean A_1) at EO.Pdf.Internal.de.b(HtmlToPdfOptions A_0, String A_1, Boolean A_2) at EO.Pdf.Internal.de.a(bs A_0) at EO.Pdf.Internal.lr.c.a(Byte[] A_0)
And explain why it is being generated?
Thanks

Hi,
Your code looks fine. You may want to run a package monitor to see exactly what your web server is sending back to to the converter. Maybe that will reveal the exact reason why the converter rejects the document.
Thanks!
