I've been using Wireshark to check out the traffic on my home network. Fairly recently, I started getting a bunch of junk generated constantly. I've been unable to find out the cause, as virus/spyware scans have done nothing and there doesn't seem to be much definite information online.

Here's an example of what Wireshark reports: TCP 63187 > park-agent [ACK] Seq=669 Ack=208 Win=17312 Len=0 is my computer, is the router. The park-agent port appears to be 5421. I downloaded TCPView to see if it could help me find the the source, but I got some pretty vague answers:

[System Process] 0 TCP 63267 5431 TIME_WAIT

I can't query it for any more information than that. I've tried ending the process from within TCPView but it just seems to pop back up. Does anybody know if there's a known cause behind this behavior?

I'm currently running Windows Vista (home).

Have you tried running "netstat -b" as administrator? What does it report? – Tog Apr 23 '11 at 8:08

Running Windows 7? Try disabling the "IP Helper" service and see if it goes away. This is assuming you're not using IPv6 in any way.

Running Windows Vista. Sorry, I should've specified in my main comments. Updating. Is this still relevant for the Vista OS? – KChaloux Apr 23 '11 at 6:05
I believe it is. – LawrenceC Apr 23 '11 at 14:22
