>It wouldn't bother me at all if it forced it to a set name, for that matter (I can always grab the file and change the name), but I do need to be able to fully automate the process. Any notion of what I'm missing here, how to proceed, or any Acrobat / PDF resources I can tap?

You can control this with an ini file for Acrobat. Check out Rick Strahl's wwPDF class for details. The class is for VFP reports, but you should be able to get the logic to work for Word.
