Why would they still not be ready, after several days respite? As I understand it, the worm doesn't do any damage to the computer, but just overloads the network. All they would need to do is clean up and install the security updates they neglected to install earlier. And the more servers install the updates, the less trouble the others should have.

I have had times when putting in a patch has solved some problems but created others. I believe Service Pack 4 did this on Windows NT 4.0.

Installing any sort of patch on Microsoft systems requires careful planning, and ensuring that its impact on functionality is not going to be negative. We are talking about mission-critical systems here.
