I have heard a rumor that XP will keep checking with microsoft to avoid piracy.
It sends info about your hardware & software installed.
Or... Perhaps somebody installed some backdoors on your machines.
It looks like a colocated machine.. here is traceroute.

It seems to be in Onecall.net's lan here is what dig says.

Unless MS has colocated a server to do the rumored XP stuff.. Maybe has cracked a server on onecall and is using it to backdoor into your machines.

Subject: Phantom connections to 216.37.13.59 & .196

Hi.
We've noticed that some of the winXP boxes inside our LAN mantain
several connections open to 216.37.13.59 & 216.37.13.196, port 80.

Those servers do not get identified with reverse dns, whois nor
traceroute.

We have thos phantom connections even in boxes without any program
except the OS itself running. Furthermore, netstat says those
connections do not exist...

Does anyone know what are those connections?

Thanks.
