I'm trying to implement an internet switching tool, our Proxy servers are
FQDN's in our DNS server.
To disable the internet for a suite of PCs (who use a particular proxy), we
are changing the DNS IP to something invalid.
However, what I've found is that IE6 seems to 'cache' the proxy settings.
(We aren't using automatic configuration scripts or anything - just manual
proxy settings).
I have the 'Disable caching of Auto-Proxy scripts' GPO setting enabled,
hoping this would solve the problem - but it hasn't.
Does IE actually cache the proxy lookup (The DNS records have a TTL of 1
second, even with a 'ipconfig /flushdns' - IE still gets through) somewhere
and if so - how can I clear this out?
It seems that shutting down IE6 and re-opening clears it, but is there
something I can do to make it more 'instant' - rather than getting people to
close IE6 (which if we disable the internet, they won't want to do as long as
they can still GET the internet)?
