hosts.cfg and ping question

[Julie Catellier]

Ok, what makes me think that it is not working?  When I bring up 
one of the status windows, i.e. 'Host Detail', the smtp servers 
show 'PING OK..'. When I select an smtp server, 'Host Checks' and 
'Host Notifications' are enabled.  The other servers show '(Host 
assumed to be up)' and the 'Host Checks' and 'Host Notifications' 
are disabled.  I looked at the retention values in Nagios.cfg.  The 
retention_update_interval=60 and use_retained_program_state=0.  I 
have also restarted nagios mulitple times.
Can you see something that I am missing from this description?
