Solution: track back the packets by MAC address to find the infected machine. Turn off NS resolution of windowsupdate.com to 127.0.0.1.
Note that the MAC address only gives you the next hop. The infected machine may be on some remote network, 20 or more hops away. Real Solution: Block packets sourced from 127.0.0.1 at your border. Drop and ignore them if the source port is 80. Invoke curses from deity of choice on admins/owners of systems that have somehow STILL missed both the security fix and the antivirus updates to deal with blaster....
