# IGNORE ICMP BROADCASTS
echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts
Try changing that line it's the only one that refers to icmp request.
Just 'echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_broadcasts'
I don't even have this file. What version OS are you running?

absolutely right, I have a standby Windows 2000 Advanced server with ISA
installed for the same operation and the same network, and when Linux server
breaks down I put this server up, and I am facing no issues with it...so
there has to be something wrong on the Linux Box which I am not able to
figure out.I am an fan of Linux and when stuff like this happens it really
upsets me...hence these discussions!!
