I am shooting in the dark here:
Do you have spaces in the linked PDF file name? If so, replace with an underscore.
Sometimes too many characters in filename can be an issue also.
It all depends on how you are going to distribute the PDF.
%20's usually need to be replaced by underscores... but you don't want to do that in your file server.
If you are sharing it via the web, then upload the PDFs you want attached and link it that way (URL).
Thank you for the replies so far. The document is getting distributed on our intra-net. The issue is when we export from inDesign to a PDF it tries to convert the link to a web address instead of a file destination even though we set it up in inDesign as a file destination. It seems like it is some sort of bug in the export process. I am looking for a work around besides creating the links in the PDF document after export since this will create a lot of maintenance every time we export the document.
I too am having this same issue. Did you ever find a work around for this. It seems strange that it would force the % in where a space is and it is completely unrealistic to have to go in and change all of the name locations for something like this, especially if it is on a windows network.

It's pretty standard stuff, actually, when it comes to hyperlinking. Spaces aren't allowed in links. Best to avoid them altogether.
