DHCP Server

Scenario:

The infastrucure is a mixed domain consisting of NT 4.0 controllers and 2000 member DHCP and DNS servers. A 2000 server is in a domain, the NIC is statically set, the second one is disabled. Why would the box still pull from a DHCP server.The leases point to the MAC on the NIC that is static. Ipconfig /all confirms the static entry on the box.
