Hello Yesterday I swapped the IP addresses of two machines ( new and old mail server ). After I rebooted the two machines I was unable to join our DNS server ( even to ping it ) I suspect the DNS was keeping the IP / MAC address mapping of the two swapped machines , so I flushed the ARP cache but it was still impossible to join the DNS from the concerned machines. I have to reboot the DNS Server to be able to ping it and use it again. The DNS server runs FreeBSD 8.0-RELEASE-p4. Thanks for any infos.
