While that's one of several locations for proxy settings, you will not find 
that the auto-detection mechanism changes this value at all.
When using WPAD, the proxy used by the browser depends on:
1. If the wpad mechanism worked at all
2. how the resulting script behaves

Bill,
If you look up the link I sent, there are 2 registry entries created by IE. 
That's where the auto detection settings are stored for wpad. You can see the 
proxy server name there.

HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections

DefaultConnectionSettings
SavedLegacySettings

10-4.  However, in those cases where the browser doesn't actually get the 
setting (because of whatever local issue) or you are troubleshooting why a page 
will not load, is there any way to tell what the machine currently thinks the 
proxy server is?  Registry perhaps?

Thanks,
Bill

You never will see it in the IE settings, because that's not how it works.

http://wpad/wpad.dat will (should) get you the proxy script that the browser 
gets.

I had previously followed the instructions for setting up auto-configuration of 
the proxy server in IE (wpad entries in DHCP/DNS).  At that time, it had mostly 
worked, but I had a few clients for which it did not.  I therefore setup a 
group policy to fill in the proxy server.

I am working on upgrading to ISA 2006 now and looking to revisit the issue.  
The one thing that I note is that the auto configuration overrules the setting 
in the proxy server field.  (At least that is the way it appears to be working 
on my workstation.)  It is also my observation that the name of the proxy 
server used by autoconfiguration doesn't populate anywhere in Internet Options 
(at least not that I can see), which leads me to my question.  Is there 
anywhere that you can see the proxy information that is actually being used (as 
received through auto-config)?  I want to be able to confirm that I am going 
through the proxy server that I think I am going through for testing purposes.  
Thanks!
