For information, I've tracked down two (Windows98) clients which
appeared to cause the highest smbd CPU usage (due to repeated
api_DosPrintQGetInfo calls) and found an identical cause on each:

  Background "adware" from "Alset", HelpExpress running the processes

If I find any other similar causes I'll update the list,
