Julie,

To add to Tim's comments.   The TSM B/A client processes all system
objects which are active on the machine; there are now a total of eleven
of these system objects (added the WMI db support in TSM 5.1.0) of which
only a subset will be valid on a given machine.  This subset depends both
on the flavor of Windows 2000 installed (e.g., Pro vs. Server vs. Adv.
Server ...) and which Windows components are installed (e.g., Active
Directory is available with the W2k server edition but only active if it
is installed).  You can expand the System Object container in the Windows
B/A GUI to see which system objects are active.  Also, you can issue the
command SHOW SYSTEMOBJECT (not documented) and see which objects are
active:

stat    rc      system object
----    ---     -------------
OK      0000    COM+ Database
OK      0000    COM+ Database
n/a     4312    Certificate Server Database
OK      0000    Event Log
   ...
OK      0000    WMI Database
