Unfortunately that is not proof that you will have connectivity
using the iexplore.exe module (e.g. when a firewall doesn't
allow it to use any outbound ports).

Only if the app being used to do that is iexplore.exe. Is it?
I have seen signs that Vista uses a different app?
Does IE7 on Vista still have the Tools, Windows Update
menu item? What happens if you try that? (Symptoms in detail
please.)

Others have found that disabling a software firewall isn't always
complete. They have to uninstall it (sometimes uninstall it using
special tools) to be completely rid of its interfering effects.
In any case are you sure that you have *allowed* the current
copy of iexplore.exe to be used over your firewall? The usual
problem is that the updated iexplore.exe is regarded a possible
Trojan until the user allows the modified version to be used.

This is really a problem with your security or networking
and not just IE so you're more likely to get informed help
from a newsgroup which specializes in it. I don't use Vista
or your firewall app. Cross-posting to Vista Networking
for convenience.


Good luck

Exactly; that's why this is not just a loose cable, a bad IP address, or
some obvious network setup problem.

Windows Update works fine both through IE and from the start button!
So, other apps access the internet just fine, showing (I think) that the DNS
isn't hosed.

Yes, I'm trying ever-more-drastic uninstall/reinstall scenarios using the
removal tools from the Norton (I used to have Norton IS -- argh, but another
story) and Kaspersky.

I really don't think it's a networking problem. Somewhere on my box, a
"security" component is discriminating against the updated IE. I have
disabled KIS's firewall, even exited the program and looked to see that the
process wasn't using CPU anymore. I've tried disabling both KIS and Windows
FWs. No joy.

Thanks! I think I need it.
