Adapters not binding to DHCP

I am a MCSE student and I’m trying to get my NT4 server to dynamic IP’s to my Win2K.
In services my DHCP server is set to auto,set scope limit to my W2K IP address only including subnet mask,duration=1 day, scope options=003 router-IP address Value in Array Editor is the gateway add.This doesn’t seem to work, tried ipconfig /release and it says that “no adapters bound to tcp/ip are enabled to DHCP” ?? I’m using an NDC card.. everything normally works in static settings ! Can anyone help.
