Netware 6.5 SP5, ZFD 6.5 SP2, Windows XP SP2, Dynamic Local Users (not

I've got some laptops that we want to detect whether or not they're
connected to the Corporate LAN so we can then determine which application
we want to the user to be able to run (set via "Remote Alternate App")

When I set "Configure remote access detection method" to prompt it works
fine when the Laptop is connected to the network (and I select slow or
remote connection) the "disconnected" app runs but when I reboot and unplug
the network cable, it still runs the "connected" version of the app.

How do we get the application launcher to prompt when the laptop is
unplugged from the network? Apps are being cached (can see them in the NAL
Cache folder....)

Any suggestions gratefully accepted!
