From: "XP Guy said:Is this optional network item:
Internet Gateway Device Discovery and Control Client
Necessary for DHCP to function on XP-SP3 ?
What exactly won't the system be able to do if that item is
un-installed?
David H. Lipman said:No. TRhat's SSDP and uPnP and will allow the desktop client to
communicate with the Router such that certain programs can
communicate to Internet resources through NAT.

The loss whould be control of software that allows some programs to
work through a NAT Router.
So configuring the port-forwarding on a router could not be done
"automagically"?
So something like a bit-torrent client would be a bit harder to set up?
Are there still BT clients floating around that need to have ports
opened/forwarded? I haven't seen that in a long time, at least 5 years
or more.

I assume that software that needs to change the settings on XP's
internal firewall is not impacted by the presence or absense of the
"Internet Gateway Device Discovery and Control Client" (IGDDCC) service
- yes?
I mean really -> what other commonly-used software needs to fiddle with
the settings of a residential gateway or router?
And in a commercial or corporate / institutional setting, is there a
compelling reason or need for this IGDDCC function/service to be running
on a user desktop computer / workstation?
That's because most of them are now using UPnP to do the port forwarding
themselves. If the OP turns off the services associated with UPnP, then
those clients will be affected.

Char said:I don't have much experience with BT, but I have uPNP disabled in
the router and uTorrent works fine, so apparently it's able to
figure something out. A few years ago I tried a client called
Azureus, or similar, and it too worked fine without uPNP enabled.
Your router is not forwarding any ports that you might have set up
manually, in the past, for BT?
I'm pretty sure that bit torrenting requires port-forwarding.
You should fire up a BT client and then log into your router and see if
any ports are being forwarded while the BT client is running.
Char said:I agree that it used to. My son used to use it in the era of 2001-2004
and I had to forward some ports for it to work for him. That's not
required anymore. I haven't done a packet capture, but I suspect the
BT client is simply initiating one or more outbound connections, which
of course become two-way connections once established. Port forwarding
isn't required in that case.
It still is. Just think what would happen, if everybody did *not*
open ports - your outbound connections would not be able to connect to
anything. The only reason that BT works in your case is because your
client connects to people who *have* some ports open / forwarded.
Nobody
can connect to you from the outside, though, and the quality of the
torrent suffers, You get half the connections you otherwise would.
Depending on the torrent, the speed can be much lower. I can attest that
I get much better torrent speeds at home, where the client configures
the UPnP router, than at work, where there is no UPnP device, and the
only connections of my BT client are the outgoing ones.
