A much simpler mechanism than that described by SANS is to have a small,
cheap NAT box in your bag (e.g. D-Link DI-604 or similar). Worth the $50
cost to have one available. Put the little router between the new machine
to be brought up and whatever network you have access to. Now you can bring
up the new machine and update it without having it get instantly infected.
(Use some common sense... don't set up email until the machine is patched,
or use any other sort of mechanism to pull in potential viruses before
patching is done).

The risk is smaller, but still exists if you follow these directions
for XP pre-SP2. See the Microsoft release notes for XP SP2 for details
about the fix.
If you do not have XP SP2, you need to disconnect your computer from the
network prior to every boot cycle until it is fully patched.
(To deflect the inevitable "NAT is not a firewall" complaints, the box is a
stateful inspection firewall -- as all NAT boxes actually are).
