I'm not certain that this is going to lead to the final resolution
because we have had at least 2 cases where the microsoft box in question
had not been moved. They were office workstations that had been in
place for some time. It is possible that they got leases from rogue
DHCP servers and then were exposed to "share network". I'll certainly
look for that in the future.
