Ok, so xinetd is not a problem.

What kind of network is between client and the server (you mentioned
using a client on a Windows box, and server is Linux)? Is it direct
connection via LAN, or you go through something like Internet, ADSL,
VPN, whatever?

Check the output of this command:

# cat /proc/sys/net/ipv4/tcp_keepalive_time


Also, are you sure the problem is on the server? There are some Windows
firewall software that also closes the connection after some idle time.
