Hi,

We have recently migrated all of our websites from Server 2003 to Server 2008 R2.  Originally we were encountered general problems with PDFs from all our DNN sites that had links that displayed pdfs.  We have found a way around that by creating a new handler for pdf files.  This has been working error free for about 5 days now.  Today we got a call from a client which uses Document Exchange.  Thier error is not as cut and dry as the other clients.  The old problem was NO pdfs were being displayed, now the problem is some pdfs are not being displayed from within Document exchange.  No errors are thrown, the pop up window comes up, and just appears to never complete.  The reason i am even thinking it may be a problem with the document exchange module is the same pdfs will display on the same DNN site if I add a hyperlink to the page to open that pdf.

Some other wierd behavior, if the client clicks the link, some pdfs do not display (this is the one i mentioned above) but if the user clicks the save icon beside the pdf, and choose open from the open/save dialog, this seems to always work as well.  Has anyone else experienced this problem?  Is this a known bug with IIS 7.5 and document exchange?  I have performed serveral tests this morning and feel pretty good that our pdf handler is working fine.

Any help would be appreciated!

Brian

I posted in one of the other forums here about this exact same issue last week.  We're running DNN 4.8.3 on fully patches Win 2003 (IIS 6).

One interesting thing I noticed is that the PDF links seem to always work in Safari.

Skimming the forums, it looks like Peter hasn't replied to anyone since the 6th, so I am assuming he is on vacation.  Hopefully he'll return soon!

Hi guys,

I was away for OpenForce US. If you ever get a chance I'd recommend going. About the PDF issue: this is something that cropped up recently and has to do with the way the new IEs and Acrobat play together. I have a fix in the pipeline. What happens is that the browser does a partial request and only sends that bit to Acrobat. If you download and open everything should be fine. Just double clicking on a PDF that you've opened before produces this error.

 Do you have an ETA for the release with this PDF fix?

Hi Brian,

AFAIK it's solved with the latest release. Clear your browser's cache and try again. Please let me know if it persists. The error we were able to reproduce here which looked like your issue we managed to resolve. But we don't exclude Murphy's law in this type of matter.
