The first thing I would suspect is the termination. Make absolutely sure that the system is terminated properly. I've seen many strange problems with a chain that isn't terminated, or terminated incorrectly. I won't bore you with the details of how this is accomplished, but I'm sure you know how. Just remind your friend to make sure both internal and external is terminated properly.
