Hi, Paul -

SSDP (Simple Service Discovery Protocol) uses port 1900
to discover upstream Internet gateways. Disabling the
Universal Plug and Play (UPnP) service will stop the
chatter - but I don't know if it'll break your network.
It depends on how your network is configured.

If you're on a private network I don't think the traffic
passes through the router but maybe someone who's a bit
more familiar with UPnP can provide more information..

My suggestion? Either disable UPnP or block port 1900
and see if your network breaks. If it doesn't, leave it
blocked - you can always put it back the way it was ;-)

Hope this helps -
