According to the IBM Technote located here:

Backup

These two fixes are VSS fixes necessary for TSM.

Subsequent to Win2k3 SP2, Microsoft has provided VSS Post SP2 fix
packages: 
KBASE# FIX #
--------------
940349 unknown
934016 unknown Note: This is a COM+ rollup package required for VSS


The Technote implies that 934016 is required.

However, on Microsoft's site, the KB link
http://support.microsoft.com/kb/934016
says:

A supported hotfix is available from Microsoft. However, this hotfix is
intended to correct only the problem that is described in this article.
Apply this hotfix only to systems that are experiencing this specific
problem. This hotfix might receive additional testing. Therefore, if you
are not severely affected by this problem, we recommend that you wait
for the next software update that contains this hotfix.



Which one is "right"--  do I apply 934016 because IBM says it's required
or do I wait until a production server experiences the specific problem?
