No, that can happen, and alot more than folks think. One of our policies is that a machine be completely patched before it is connected to the network.
Let's say there's a critical update that patches a machine from getting infected by a particular worm. The worm is on the network. Once that sucker's plugged in, it's a matter of seconds. Actually, I've seen a machine become infected almost immediately. Brought it up, and the Messenger Service brougt up an error informing the user that such and such was detected by the AV app and removed.
Patch em as best you can before connecting them to the internet. If you have a Broadband router and you know the other machines on your network are clean, you don't run as much a risk as with a machine that's directly connected ditrctly to the internet, an unsecured network, or a large corporate network where chances are that worms are on the loose.
