Agreed, and hibernating laptops too- I think it should be a rule that some
sort of extra laptop/VPN behaviour must happen on days like that.

Worse (in terms of damage) was RDS, which was patched years before there
was an exploit, but exploited more than anything else until we got the
.printer stuff.

Yes, but if you look at all the patches and DLL versions, it's a twisty
maze of patches, all seemingly alike.

For instance...

Is a post to NTBugtraq that details the versioning thing[1]. Clear as
mud, and I'm not at all surprised that MS-based admins had trouble with
untangling the patch issues surrounding this thing. Trust me, the primary
data Russ used to get to that e-mail wasn't nearly as easy to figure out
as it looks. ;)

Not only that, I think we can summize by the 9AM Monday in Australia
upshoot that MSDE was a bigger factor than SQL Server itself- and patching
that wasn't a trivial task _if the user even *knew* it was necessary_--
Now, I don't use MS Project, but if I did, I don't think I'd assume that
SQL Server issues would affect my desktop.

Worse-yet, there are still third-party products where the vendor will *not
support the product* if you apply the patch. Everything from CRM
applications to door badge readers- there are raftloads of vendors of
turnkey (or not) applications who aren't supporting customers who know
they need to patch, let alone encouraging their customers to patch.

Didn't at least one of these patches have a memory leak associated with

While I'm sure there needs to be some sort of patching discipline, it's
not a simple or clear-cut thing.
