DNS Report: Interesting Name "JSPNRMPTGSBSSDIR"

[Ian Castle]

Apologies if this is off topic for this list!

I was looking at the sample DNS report on the website 
(http://www.logreport.org/reports/about=dns) and this bit caught me eye (or 
rather google brought me to it):



      "JSPNRMPTGSBSSDIR                              7
              Nice name, would it have any meaning?"

I've just been bitten by this particular name (JSPNRMPTGSBSSDIR).

Until last week we were running an internal root server on our intranet - so 
that only our local domains could be accessed.

Because bandwidth costs have dropped (unmetered ISDN) we've just changed 
things so that external queries are now forwarded out to the net.

Every two minutes there was a query for the above name.

In turns out to be MS Windows NT's RAS service which tries to resolve this 
name every two minutes. It first queries the local domain e.g. 
JSPNRMPTGSBSSDIR.example.com, then the next domain up e.g. 
JSPNRMPTGSBSSDIR.com.

I've worked around this by adding an entry to our local DNS (A 127.0.0.1) 
which effectively shuts this up - once the name has resolved it seems to stop 
querying it.

It is especially annoying when you are using a dial up line so might it be 
worth documenting in the DNS analysis report?

MS has some info about this at
