A client of ours has one XP workstation that is attempting to open
thousands
of internet sessions. This has the affect of flooding the network
with
unnessary traffic. This was causing the old Netgear router to crash
and we
have replaced it with a more sophisticated Draytek which has
identified this
XP machine as the source of the network traffic. We have put a
restriction
on their router to prevent this machine from opening up too many
connections,
which helps the other users on their network, but this machine needs
to be
stopped from doing this.

I have used the usual suspects (Process Explorer, Auto Runs, AVG,
MalwareBytes), but am unable to find the culprit on the machine that
is
causing the problem. Can anyone suggest other utilities, procedures
to go
through that might help.

Physically unplug it from the network!

Other than rebuilding the machine?

Rebuilding *shouldn't* be that difficult.
