I agree. Currently, I've seen 601 attempts to pass traffic to port 135 since
midnight and climbing as I type. Most of my denies today have been target to
ports 135, 445, and 137-139. Although, with a fair amount of new systems
purchased at Christmas, I expected it to be much worse than it actually is.
Could it be that folks are actually starting to be concerned with their
systems as the new generation(s) start to take to the net?
