I have an C# .NET remoting app/server that is sometimes inside the domain on LAN and sometimes outside on WAN. 1) I would like to
easily detect the IP connection status (See footer notes).
2) I think I would like to be able to pop up the standard Internet Auto-Connect dialog IFF no connection is detected (i.e. remote
connect times out, or actual IP connection status check). It seems that this will be unmanaged code as I haven't found any
framework help in my searching, just the various RAS, WSOCK, etc apis.
I was half hoping that just setting up internet networking to auto-dial when necc would pop up the connect dialog when I tried to
open up my TCPIP channel and there was not a detected network connection (Yes... I'm gullable and a bit lazy).
Q: Has anyone done something similar or have another approach or ideas on auto detect and connect LAN/WAN?
