Annoying dynamic DNS updates

Some cable user's machine running default-configured MS apps
is sending Paul dynamic DNS queries that it shouldn't,
because somehow it's decided he's got an interesting destination
(I'm guessing f.root-servers.net ?)
Paul wants the user to get an error popup about it.

Well, default-configured Microsoft applications have an
application that lets you send a machine popup dialog boxes;
it's been discussed here recently because spammers abuse it
and (related discussion) it uses Port 135, so it might or
might not be blocked by Comcast.net. So the obvious thing
to do is find whichever program it is you use to send those
messages, and start sending popups, guessing that it might not be blocked.
The user's unlikely to have a clue what to do about them,
but if you include a URL, you may get their attention.

It would be amusing if said "popup spam" got Comcast's attention,
and they contacted Paul about an "urgent matter"...

anyone who doesn't have the windows messanger service disabled or
fire-walled. gets huge piles of messenger spam so it will look just like
more messanger spam to those people.

135 is, indeed, blocked by Comcast.

135 is, indeed, blocked by Comcast.

What about ICMP (24.218.168.0 subnet) ? I was informed ports 135-139 and
4444 were blocked only.
