I will do that. I don't think the conseqences are any worse than a loss of
connectivity - I can see no way that data corruption can result.

I have no reason to suspect the network. It carries tens of gigabytes of
traffic every day with no other problems. The server in question handles
several other IP-based services with no problems. I have no reason to
suspect the server hardware since the problem has existed since before the
machine was replaced a couple of months ago.
The problem is limited to machines on the same subnet as the server. It
does not appear to be limited to any particular model or OS version, and
only happens to one or maybe two out of the 100 or so machines in that
subnet.
The problem cannot be reproduced on demand. I guess the next step is to
plug a packet sniffer in and capture all the aarp packets for a while.
