Exactly. You don't do caching on computers that won't ever come off the
network. i.e. don't do it on desktops. If you have that much of a problem
with AD being unavailable, you better look more closely at your AD
architecture.
You may do caching on laptops, and then i'd hope you don't have people
sharing laptops. If you do, well then, that's another story requiring
careful consideration, but a little off-topic.
