Windows Hangs at reboot for update KB929451

Yesterday I had 5 computers hang completely after a reboot that applied
Windows updates.

All machines running Windows Vista Ultimate. A mix of Dell Optiplex 745 and
755. All of them would not begin to load windows after POST - even after
several hours. Forcing a reboot, recovery options necessitate a restore to
an earlier point.

Taking one machine out of the loop, I was able to apply the Windows update
and cause the error repeatedly. I finally started applying them one at a
time and isolated the patch to be the one associated with KB929451 which
fixes something with bad IP addresses after changes to the GUID of a NIC
card. It is listed as an important update and came automatically.

Anyone experiencing something similar to this? I fear what will happen with
other reboots – it has been hit or miss if the box survives the update.

KB929451 has been offered by Microsoft Update since February 2007 (Source:
http://support.microsoft.com/kb/947503/en-us). Why was it just offered,
over a year later?

Do these machines update via WSUS?
