I don't know why font replacement wouldn't work right, but thanks to Arnis Gubins I figured out that the fundamental problem was that the documentation department's master font directory contained only ZD______.PFM, not ZD______.PFB, so the Type 1 version of ZapfDingbats FrameMaker was expecting did not get installed on my PC.
