Sounds as though the names are being written in Unicode, which sounds like 
the wrong thing to do in this case.

Hmmm... Unicode *and* lower case.  Probably both wrong...

Ethereal is free, by the way, and it is a common tongue for folks on this 
list.  :)

Anyway, yes...  The Unicode bit in the Flags2 is set in the second example 
(Samba 3.0).  The messenger service is old, and probably hasn't been 
updated for Unicode, so I think that this is wrong.
