XP ICS UPnP Host not working...

[Guest]

For the last 4 months or so, i've had a laptop setup as my router using
Windows ICS. At some point though, all of my machines stopped recognizing it
as a UPnP host. I've tried enabling/disabling windows firewall, and also
re-ran the home network wizard to make sure everything was set back to
defaults. UPnP and SSDP Discovery services are running. Manual port mapping
works fine.

I am connected to the internet via Sprint Mobile Broadband, which basically
just creates a Dial-Up Networking connection, which I share out via ICS.
There is no software firewall running. My NIC is setup as 192.168.0.1, and
is connected to a switch, which connects the rest of my machines. Both
machines (one vista, one XP) are setup with static IP's, and my Xbox 360 is
dynamic.

Is there anything else I can do to revive UPnP capability?

Checked your PCs for anti-virus software that may contain a "hidden"
firewall? Both McAfee and Norton have modules which behave just like
a firewall but are "named" differently. In Norton, the module is name
"Internet Worm."

As I stated, neither machine is running a firewall, whether it be built-in
or 3rd party. The Vista machine isn't even running AV, as it's pretty much
just a test machine. It dual boots with XP, same behavior on both OS's.
