Our network is W2K network. There is no any issue when we use DHCP. But if we change DHCP to static IP, servers will perform strange. We can ping it in the first ping, but not the rest of three. After that, I can not ping it anymore. If I reboot the servers, it repeats above. Sometimes after reboot, we can ping for a while. Then network connection is lost again. Also when we click on anything on the servers, it seems it takes a long time to response. This happens to either W2K3 or XP OS. Also sometime, you can not ping the server, but from that server, you can ping other servers on the network.
I’ve already ruled out any switches problem. All servers involved are in the same subnet.
Thank you very much in advice.
