Hi Damien,
What interface is the network connected to that you wish to serve DHCP
addresses? You mention eth1 in your post, but I only see eth0 and eth2
configured for dhcp-relay. If you want to serve hosts behind eth1, you
need to add eth1 to the dhcp-relay configuration.
To make this more clear, if your win 2k3 server is configured with a
DHCP scope for network 192.168.10.x, it will only serve requests made
from the interface configured with 192.168.10.x. The dhcp-relay adds
the IP address of the interface that requests are seen on into the BOOTP
request packets so the DHCP server knows which scope to serve addresses
to.
Thank you,
Robyn
