I suggest using Microsoft Network Monitor
(http://www.microsoft.com/en-us/download/details.aspx?id=4865) to identify
the processing sending out that traffic.

Subject: interesting multicast packet
my google-fu is failing me, but maybe one of you knows.
After some troubleshooting around a Juniper SSG cluster today, we found
that a windows server on the trust side of the SSG cluster is emitting
UDP packets towards
ff08::2.8083 (UDP, payload length 21)
ff08::2 = "all routers, organization-scoped"
These packets are sent about every 61 minutes, and caused some interesting
issues here as the *passive* SSG leaked them out towards the router, leading
to "the NSRP MAC address showing up on the wrong switch port", causing short
But that's not what I'm wondering about - I'm more curious about that
sort of packet - what is that? What is it used for? Which process is
emitting it, and what is it trying to achieve?
have you enabled IPv6 on something today...?
