Multicast

Hello,

I hope somebody can help with this weird problem...

I have a Win 2000 server, DHCP, WINS and DNS. The internet connection is a
DSL router. A few days ago we started to have problems going out on the
internet. Nothing in the configuration had been changed and everything
looked normal. In network monitor I noticed a lot of multicast traffic (over
3000 packets/sec). If I restart the server, for the first 5-10 minutes
everything works fine until the multicast traffic starts. I can't figure out
what can generate this much of multicast traffic.
Can anybody help?

Thank you.

Catalin,

That is some Multicast going on there. Do this, in your network monitor
capture some packets and look to see who the source of the "group". Some
system is sending requests to "joined" machines. You are looking for the
originator. Possibilities: Someone is playing a really cool game, streaming
server or who knows, but first things first, get a "sniff" of a few of those
packets.

Take care

Alex Paoli
