Any computer running Office XP Developer Edition, Office XP Professional Edition, Sharepoint Team Services or Visio 2002 will probably have MSDE 2000 installed.
This is the client computer, stripped-down, version of SQLServer which acts as the underlying database in these environments. MSDE 2000 is subject to the same problems as SQLServer with regard to this worm.
Better check if those boxes have MSDE 2000 installed on them.
