Mario - I shudder to think of this cause, but...

It may be the case that some spud in your shop decided to set up a Windows box
with the same network address as your prevailing AIX system.  Or some network
reconfiguration went awry.  I would recommend poring over your TSM server
Activity Log for the times and network addresses when these sessions occurred,
to see if this is indeed the case.  You may have to get your network people
involved, either to identify the perpetrator or examine their change logs for
any work they did which corresponds to that date.  (Whoever was operating the
NT system would seem to know client passwords.)
