Hi,
I have a small network with 10 pc. The broadband line is connected to a small router (IP: 192.168.1.1) which has 4 ports. One port is connected to one pc which has ip addr 192.168.1.2 and another port is connected to a hub with 9 pcs. The other 2 ports are free. All of my computers have different host name and static ip (previously they had same host name). Now some of my computers show the ip conflict message. I did arp -a command to look for the problem in one of the affected pc. The physical address information do not remain same in every arp -a command, it sometime shows the real mac addresses of other computers, sometime it shows an specific mac address at the place of physical address information of several computers. After deleting the ARP cache I ping all other computers to feed the arp cache. But the problem remains same. I cannot figure out why the mac address is different than the original one in the arp result and why I get the ip conflict message very often in several computers. So what is the possible problem? How can I fix it to get all time internet connection in all PC?
