Hi all

I have been running Windows XP Pro with SP1 for a short while now, but
my firewall keeps picking up that various Windows services, etc. are
trying to broadcast to ip 224.0.0.22, whatever that is.

What have I done to instigate this and what can I do to stop the
broadcast happening?

Many thanks

It's part of multicast, I wouldn't worry about it.

Thanks for the reply.

Hmmm, strange. On my old Windows 2000 I never had this broadcast being
picked up by my firewall. Is there anyway I can turn off multicast in
Windows XP?

Thanks

Most likly uPNP - disable that and the "problem" should go away. If you are
behind an ADSL router you will lose the automatic port mapping that makes MSN
messenger and some P2P programs work correctly however.

Thanks for the reply.

If I understand you to mean by uPNP as Universal Plug and Play, then
that service is already disabled.

Maybe the 'Internet Gateway Device Discovery' client is doing the
broadcast query

Maybe there are other UPnP devices on your network?
