Host check clarification

[Steve Dix]

I am new to Nagios and have over 100 hosts that I am checking.
Everything is working fine with the hosts check except I have 1 host that will go "down" and then next immediate check be "up".
This happens several times a day but the host appears not to have had a problem.
 
Any suggestions on what to check to resolve this problem as I suspect it is the host (Windows 2003 Server) not a network level problem.
 
thanks

I need some clarification as to how exactly the host check determines  
if a host is down. In the default configuration, the check-host-alive  
command sends a single ping, which can be considered (obviously)  
either ok, warning, or critical. The host then has a  
max_check_attempts setting of three, which if I understand things  
correctly means it will try this check twice more, in rapid  
succession, before putting the host into a hard state. My question is  
what is the logic if one of these three checks returns a different  
state than the other two? Say, for example, the first ping never makes  
it back, therefore returning a critical state, but the second and  
third come back, giving OK states? is the host then considered up or  
down? Thanks!
