OK- Some more info... I tried many of the previous recommendations:
Interact with Desktop, verifying service startup, removing updates,logging
off and back on, etc... Nothing changed. Verified on a SNAT client on the
main segment as well (my testing here done with ISA Firewall Client)- no
updates listed.

I fired up my trusty "NGS Sniff" Win2k/XP sniffer while starting and
stopping the service, etc with nothing.

Then I disabled the FW client, and dialed into my local backup ISDN
provider via a Network Connections Dial-Up profile (Firewalled) , and
started NGS Sniff again on that IP. After waiting for about a minute, Auto
Update content started streaming by. Note that I did not have to go into
IE or anything- just connected. I've got the entire transaction dump saved
now and will share it once I see that it does not contain anything I don't
want out there... It successfully downloaded the content, and then notified
me that the updates were ready.

So, in my case anyway, it seems as if it checks only on an active "Internet
Connection" and not on the LAN connection. It is all done over HTTP 1.1,
port 80. I will try some other things, but I would say it has something
to do with Local LAN vs Network Connections as opposed to anything
NAT/Firewall/Web Client related. Any reports as to your findings or
configs would be appreciated. In particular, I would like to see the
config of people who are using a LAN-only connection (No VPN, Dial-up
profile, etc) where autoupdate works.

Thanks to all participating in this--

Cheers
