Tcp/ip + Lan

[Waqar40]

I have developed a server which runs 8 hrs in a day, it broadcasts data after every minute to n clients. It was little about server.
Problem is when LAN disconnected server got crashed as i used TCP/IP.
How may i get rid of this problem. Server must not crash regardless of LAN Status

So you need to debug your server, find out what code is handling the condition of n/w unavailability.
