I have three computers on home, an one of them as Windows NT 4.0 Server
installed, and the other two have the Windows XP Professional with SP2, and a
create Global accounts on Windows NT 4.0 Server, but when i disconnect lan
cable the both PC's log on without the Server verification, how can i block
the log on when the lan cable is disconnect?How can i do for the other 2 PCs
log on only when they are connected to the Windows NT 4.0?

Thanks for ing me.
