The marvels of Windows. Block traffic to/from ports 13[789] from
your dialup and you should be ok - either using ``set filter'' in
ppp(8) or ipfw(8).
But hey, that won't necessarily sort it out - I still have a DNS
entry of
jspnrmptgsbssdir IN A 172.16.0.253
since the days when I had a Win95 box on my network ! Go figure.
