  As another data point:  From a border router to a
couple of low volume web sites from a "sh ip acce"
command (cisco), some of the output is:

  Extended IP access list 102
   ...<snip>...
    deny tcp any any eq 137
    deny tcp any any eq 138
    deny tcp any any eq 139 log
    deny udp any any eq netbios-ns (86271 matches)
    deny udp any any eq netbios-dgm
    deny udp any any eq 139
   ...<snip>...

  This router was rebooted about two months ago and
I'm still telneted in to it and another  sh ip acce
produces:
    deny udp any any eq netbios-ns (86309 matches)

  Sigh.
