>I have an application developed under 5.0. We distribute it by CD to our customers and they install it with InstallShield. More frequently of late, we've been running into a problem on some NT networks. They can install the application fine. When the click on it to run, nothing happens. But, if we have them turn their system off, unplug the network cable, and reboot..the program runs fine. When they shut down, reattach the cable and reboot again, nothing. And it isn't on all NT systems this occurs unfortunately, just at random it seems..:(

If your app works properly with the network cable unplugged, clearly it is not a network application. Having the network "plugged in" *should* simply be providing a service that your app doesn't use anyways.

It sounds like your app may be attempting to make use of network services for some purpose, *if they are available*. I would start looking there first.
