Unplugged cable.

My program works in a very "hostile" environment. Users sometimes unplug
network cables. On TCP/IP level this looks like lost connection. Is it
possible to find if the cable is really unplugged?

It is possible if you have 'Media Sense' enabled:

'ipconfig /all' will tell you whether the cable is unplugged or not.

On Windows XP you can also use NetConnectionStatus member of
Win32_NetworkAdapter WMI class to check whether 'Media disconnected' is set.
