You’re a good fella 🙂
Have a search of the forum, I other have already put it here.
If you are doing fancy things with profiles, it’s possible that you can have a user log onto a PC, download a cached sure list and their registry will store the XML version number… Then when the user logs onto another PC, their registry roams, but not the cache. In that scenario IE won’t download the XML list because it thinks it already had the latest copy.
What’s the issue that you’re trying to fix, anyhow?
