-s is expecting an IP address, not a name --

Usage: check_dhcp [-s serverip] [-r requestedip] [-t timeout] [-i
interface]
                  [-v]=20
-s, --serverip=3DIPADDRESS
   IP address of DHCP server that we must hear from

Also try adding a -v flag for more verbose output. That may provide
interesting information for further troubleshooting.

Neither do we really. Can another machine on the same subnet obtain an
IP address from the DHCP server? Are you running a firewall on the
machine running check_dhcp that might be preventing DHCP from working?
Do you see entries in your firewall logs indicating that it's being
blocked? Does your DHCP server specifically ignore requests from that
machine?
