UDP Port 5140

Hi!

When looking for something unrelated I noticed that a PC at a client
site tried to contact a machine it should not have business with ;-)

The PC is running Windows XP (dunno if Home or Prof) and it was attached
to a WLAN at that time.

bucp1-vip-m.blue.aol.com has 64.12.161.153.

Has anybody seen something like this? Port 5140 is not assigned by IANA,
and Google did not come up with anything useful.

bucp1-vip-m.blue.aol.com takes connections on TCP port 80, but is not
running a webserver there.

Thanks for any hints,
Lupe Christoph
