1. DHCP discover did receive a DHCP offer
from the server(s) the meet the clients's
requirements, but the server did sent DHCP
nak (not acknowledged) to the client's
DHCP request. (It is possible that another
client was using the address that was
served.) This usually occurs when there are
multiple DHCP servers on the same
network, and server A does not know the
subnet configuration of server B, and
vice-versa. This can also occur when the
pool of addresses is not truly divided.
The DHCP server's configuration file should
also be set to "authoritative".
2. Insure that the DHCP server is functioning
properly.
