The Windows DHCP server is "NIC aware". The two NICs he described, typically
is on two different physical subnets. If a Discover/Request comes from NIC1,
an address is allocated from the scope or super scope in which NIC1's subnet
belongs to.

For the following scenario to work, just define the proper scopes for NIC1
and NIC2 and they would just work. Make sure that NIC2's address has a
corresponding scope defined and is active. Same rules apply.
