[asterisk-users] DHCP Failure screws up system

[Anthony Francis]

Watch your router and see if the arp entries are changing for the IP's 
as this happens, I am very willing to bet you have IP address conflicts

and bringing them back up so they all get leases out of the new servers 
pool instead of being a miox between that and your old one.
