Please note that on some systems with only one active DUN connection, TreeWalk may setup your Networking Properties without any further configuration required by you. The following explanation is provided:
"The Network Configurator code already has some functions to change multiple Dial-up Connection settings but they are disabled. When the TreeWalk idea started, we decided not to tamper too deeply with dial-up connections since in some cases they're used for VPN connections and the like. Changing such connections may cause more problems than they solve, so we (myself and NT Canuck) decided to
stick with changing only the network connections and leaving dial-up alone. The problem is, that from the point of view of Windows APIs you have no way to tell if a particular dial-up is used just to connect to the Internet or to connect to a remote private network or whatever else, so it isn't a matter of "change them all" since such a thing may cause troubles for users. All in all
we'd like to avoid hearing users complaining about the fact that after setting up TW they lost their online-banking access, or similar complaints. We could as well setup a dialog asking the user which connection to modify but this may also be error prone, especially when taking into consideration that our initial idea behind TW was to provide easy setup for newcomers too."
