This has much more to with the network and routing config of the machine then anything you would (or could) do programmatically - especially from .NET code. What you want is that packets to the IP address of the server you want to upload to are always routed through the VPN interface. You'll want to search the Win2K docs, or other resources for information about routing (eg. use the "route print" command to see how packets are being routed through interfaces).
