Using Novell 5.0 with the latest Client32 on each machine. The License manager resides on the file server with a .NLM to load it. Currently ther are 16 licenses for Acad2000 and 3 for AcadM (which no one uses). It has to be installed correctly or it wouldn't work (has to be last NLM loaded when system boots) and most of the time, 12 to 15 users in it concurrently with no problem... just once in a while someone (not just one machine) crashes.
