microsoft internet explorer 6.0 is not working suddenly. The proxy settings are correct... It suddenly happened. Intranet works fine but when you go to internet site "page cannot be displayed" immediately pops up,  Proxy is set correctly, IE seems to be ignoring the proxy settings as if they aren't there. Other machines work fine, tried upgrading to sp3, this is 2nd machine to  this issue, first machine I had to reimage, any suggestions?

maybe somehow a problem with you dns?

do the DNS settings of the machine where it works differ from a machine where it doesnt work?

Hi,

Try resetting your Internet Explorer settings to their default settings.

Also, are you able to receive e-mail or anything? Has there been any other changes to your network since this started happening?

Cheers,
Perry

We are still using IE 6, becasue some of the web interface software that we use, the developers don't want to support any of the later versions.

IE 8 has a compatibility mode - push a button, and it "goes back to IE 6".  It's new, so there's not a lot of feedback about it, but from a surface view, it seems to work the way it's intended to.

I don't mean to derail this question though.  

Go to the network connections and right click on your LAN / Ethernet connection.  Click properties, select TCP/IP from that list (usually at the bottom), and tell us what those are set to.  You may need to double click.

It is set to dhcp, it seems as if the proxy settings componet of IE 6 is being ignored. Intranet ok, click on an external internet site,  you immediately get the page cannot be displayed error, like its not even trying to access the proxysvr
