I'm having a heck of a time trying to resolve an issue (and thus far Google has not yielded the answer). I have a web application that invokes a 3rd party application to display a PDF page. Everything runs smoothly on Windows 2003, but now that I am migrating to Windows 2008R2 (64 bit) the application throws the error of "The Connection was reset" when the handoff occurs for the PDF to display. I've been going through the vendor's support group, but they have been less than helpful. There are no entries in the event logs for this app, and I only have the problem when it goes to render the PDF. Can anyone provide any pointers on this?
