Exactly. Which most of the network apps should have done years ago - and whoever didn't, should do anyway (regardless of which server is it - we know Fox works just fine with any of them). The alternative, inventing a disconnected dbf operation, is just as much work, if not more, and will be powered by 1 HP (one horsepower), the guy who wrote it. Makes no sense to do that. Even running an app on MSDE or 2005 Express is better than trying to deal with dbfs which just close on you.
