Maybe he can fix it. Of course, all but a few U.S. workers would get away with such belligerence, especially since you can never find a PC support person when you need one. Honestly, folks, the field has dwindled with the arrival of decent systems management software, remote support and networks. The acronym was WINS, although I forget what it stood for. 3M has hundreds of cranky engineers who were not about to give up their Unix workstations just because some IT bureaucrat told them to.
Sweeping edicts have their downsides, but they scarcely dent the argument for standardization.
Technical workers might take support into their own hands, meaning lost productivity. And they might make a bad situation worse. But the number of users able to service their own machines is, at most companies, infinitesimal. I can't imagine DT has many Macintoshes, but that's not so much to give up. For cost-conscious managers, it's hard to imagine a program like IT Office not selling itself.
