We're having to dual boot to XP because we need legacy software that won't install to 7+. The problem is that this software uses IE and IE8 will only let us get out on the net through the search bar, all entries on the normal address bar fail.

Using other browsers on XP or our other OSs on any of our other machines work as they always have, it's just IE8 that refuses to connect.

Ping connects to anything we give it, so it's nothing to do with winsoc, just IE8

Any thought as to what the problem might be?
