Multicast

Discussion in 'Server Networking' started by Catalin Porancea, Nov 17, 2003.

  1. 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.

  2. 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
