I would dearly like to not only unplug the linux server,
but also throw it through the window of a very tall
building overlooking a wrecking yard!! But if i do, i
know that the client will lose all name resolution, which
means no internet, mail delivery, etc.
There are 2 nic in the system, one of which is disabled
through windows. The active nic ip is 192.168.254.1 and
is connected to the internal LAN.
Regards
Darren
