Maybe?

As Andreas indicated, there is some difference between your command  
line test and how you've configured nagios to check. You didn't tell  
us exactly how you tested from the command line so we're left to  
simply speculate (not good for you).

Based on this error you reported- "CRITICAL: Received 1 DHCPOFFER(s),  
0 of 1 requested servers responded, max lease time = 86400 sec.", I'd  
guess that you are getting a DHCP response but it's not from the  
server at $HOSTADDRESS$, which you've required the response to come  
from (-s), whatever that is in the matching host{} definition.

Is the slave server that you're wanting to check on the same broadcast  
network as your nagios server? Is it's IP the same IP as the 'address'  
parameter in that check's host defintion?
