Marc, that's not strictly what Olivier is asking for. Nagios will  
silence alarms if the host is down, but will continue checking the  
service, regardless of the state of the host.

Olivier, you could probably stop the service check by using  
dependencies (http://nagios.sourceforge.net/docs/2_0/ 
dependencies.html), but there's a lot more configuration required.
