What it will take to eradicate it for good is some hacker to make a more dangerous strain, one that actually wipes out the target computers, or worse. Then they'll be *forced* to patch their servers.
Or, like I suggested in another thread, somebody could modify the worm so it installs the patch itself, then reboots the server for a fresh-start. Or better yet, install Linux... ;-)
