network connectivity problem

[cranium2003]

hello,
on a Fresh newly installed Fedora core 3 server machine, i set my NIC properly so that my internal network can reach thro' switch. but what is happening currently is that internal hosts are unable to ping to server but server can ping to internal hosts.
what will be that problem and how to solve?

Pretty hard to figure out based on that limited information. Some questions: What is the output of 'ifconfig -a' and 'netstat -rn'? Are the internal hosts on the same subnet as the server? If not, are the gateway addresses set properly? If so, are all the subnet masks set alike? Are all the machines in question on the same switch? If the switch has VLAN capibility, is that being used? Need more details to troubleshoot the problem further.

Could also be an issue where the firewall on the machine is blocking ICMP requests. Turn off the firewall and see if you get the desired results.
