Jim;
Not really.
But leave the network connection physically disconnected until you have a
firewall enabled.
Install SP-2 first if you have the CD.
Then connect to the network and go directly to Windows Update and install
all Critical Updates.
Keep going back to Windows Update until you no longer get offered any
Critical Updates.
Reboot between each set whether requested to or not.
Be sure to install your anti virus, spyware killers etc BEFORE you do
ANYTHING else on the net including Email, surfing etc.
