Scvhost.exe?

Svchost stands for Services Host, so it is required for many services but now that UPnP is disabled it shouldn't be connecting.

I have said UPnP is for the majority of users an unessential service and why GRC.com gives such a strong emphasis on disabling it. If you required it you would know because you need to connect to devices over the Internet, typically if you were connecting to say a work printer. There is enough work required to set this up that if you needed it you would know.

So if you haven't already disabled I recommend you do so as you said if you ever needed it (highly unlikely) you can enable it.

This is something else again as port 53 isn't normally used for UPnP

The IP address in your image is for   Domain name: tiscali.com possibly you ISP ?
Port 53 is normally used for DNS purposes, getting an IP address for the friendly URL that you type this requires an IP address so it can find it and it gets that from a DNS server.

If one is behind a NAT router (which many of us are in these days of wireless and shared home network connections) then telling folks that turning of the UPnp service will have no effect is totally misleading.

The UPnp service is necessary for a number of (fairly well known) applications that will not work unless they have the service to help them deal with internal vs external IP addresses and the management of ports for devices sharing the connection.

Thanks Alan, since I don't have broadband and no NAT Router I wasn't aware of this and I'm not aware of these fairly well known applications that require it ?

So my assumption that if people used those applications or had a need for the UPnP service would know it needed to be enabled. Should someone require it and it was disabled then they would soon know about it and could enable UPnP.

P2P applications, for instance. eMule can use UPnP service (if the user set it to do so).

Thanks Tech, I fear many wouldn't know what UPnP is from a hole in the ground.
