Use in Windows Vista (and later)

In Windows Vista (and later), when the application is started in "Administrator" mode, the network connections may be lost for the application. Indeed, if UAC system is enabled, the network drives are disconnected when the user privileges are increased. To be able to use them, they must be specifically reconnected with NetworkConnect.
