Ongoing discussions (some lasting more than two years) in various security
mailing lists have documented repeated failures of WU "technology". It turns
out that WU was yet another Microsoft-special -- a cheap'n'cheerful "let's
make it look like we're doing something useful" project glued on the end of
Windows 98 (originally) that was not designed for serious patch management
and distribution.
For example, until _very_ recently, WU would not do anything other than check
for registry values cretaed by patch installers depite the fact that most of
those installers (also written by MS remember!) would set those values _when
they started_ rather than after installing the patch and checking that the
right files had actually become active (and, in fact, very few of the patch
installers performed the latter step anyway, as was discovered for many
failed patch installations when folk started using tools designed to make
sure specific patches were installed rather than using MS' WU toy).
It works well for me. ...
And you know this because you have independently verified the proper
installation of all your WU-deployed patches on all 600 machines, right?
Or do you know this because the patch logs say that all those machines have
been patched and none require current patches?
... And it sure as shit is better then hand patching 600
PCs.
In that case I'm guessing that you chose the second option above, which means
there are very good odds that you have something in the range of 60 - 300 PCs
that WU/SUS reports as patched to MS03-026 ("the Blaster patch") that are, in
fact not patched to MS03-026 at all (this is based on published claims of
researched WU/SUS failure rates for this patch ranging from 10% to 50%).
If you _think_ WU/SUS is doing your patching for you, then you shouldn't be
using it as it is known to fail far too often to support such confidence.
For home users and very small businesses WU is the best we can hope for, but
at 600 PCs you should be doing something competent.
