XP Proxy settings with multiple LANs

Hi

Hopefully this is an easy one:

When connected to my work LAN, my computer (XP SP2, IE7) needs a proxy
server specified in the Windows LAN settings (in Internet Options).

At home, when connected to my ADSL modem/router, I don't need this -
in fact I have to disable to proxy settings to get out through the
ADSL connection, because otherwise it just looks for the proxy server
and doesn't find it.

The question is: Can I do anything more automatic than having to go
into Internet Options, Lan Settings, and disbaling or enabling the
proxy every time I move from one network to another? Should the
"Automatically detect settings" option handle this? If so, it doesn't
seem to be doing it.

Thanks

David

If you get Firefox, this has an excellent proxy-switcher add-on. Forget the
name of the author, but it should be high on the list of popular add-ons.
