Disable Bridging Completely.

Here's the deal. When a computer runs XP Professional with two network
cards, users can mistakenly enable bridging which creates havoc on our
network. Is there a way to disable this ability to do this? Like disabling
the service, registry modification, deleting a file, or adding a policy? I
am familiar with Microsoft KB article Q283429 but this isn't a viable
solution, as they can easily mistakenly turn it on.

Thanks,
