I don't know exactly the factor that affects the recovering process.May be the recovery time is depend on the number of the clients.and in my company,there are about 500 PCs,and the recovering process costs 15min.
By the way,who can tell me the factors?

Thanks for the words of encouragement. I have let it run from an hour, and my customers are crying blood murder.
Does anyone have any idea of how long it will take to recover 125K leases.
Thanks,
Luis

Subject: DHCP Failover recovery......
a few weeks ago I posted a message about a problem that I
encountered. I had a two server dhcp redundant/failover setup and I
deleted the dhcp.leases(~) files as I did not have enough room to
save them. ( I know a very stupid thing to do. no excuses).
I have been running on a single (with none failover) dhcp server and
want to return to a two server configuration. I am not doing DDNS,
so I don't have to worry about that now. The problem is that when I
restart both servers they STOP offering IP addresses, and I see a
lot of recovering messages on the logs.
When I start the servers, the logs show the following:Jul 28 07:56:36 D4FWWC1 dhcpd: Sending on LPF/eth0/00:15:c5:fe:57:bd/10.129.177/24

Jul 28 07:56:37 D4FWWC1 dhcpd: dhcpd startup succeeded
skip a few lines and I see the same message for most of the subnets on the dhcpd.conf file.
DHCPREQUEST for 10.129.77.204 from 00:12:3f:08:0d:e3 via 10.129.76.3: not responding (recovering).
Thanks,
