Is the DHCP server running on the same system as check_dhcp?  If so,
this is a known bug, see:

http://sf.net/tracker/?func=detail&aid=1090549&group_id=29880&atid=397597

If you're checking the DHCP remotely: What operating system are you
running check_dhcp on?  Can you see the requests in the DHCP server
logs?  Can you see any replies using tcpdump(8)?
