I wondered if it could be that, but usually if I messed up
the host, it would let me know on start up.

I have this:

# Unix host definition template
define host{
        name                            unix-host
        use                             generic-host
        check_command                   check-host-alive
        contact_groups                  unix-admins
        register                        0
        }

# 'webwork' host definition
define host{
        use                     unix-host
        host_name               webwork
        alias                   (webwork) Webwork server
        address                 WWW.XXX.YYY.ZZZ
        max_check_attempts      10
        notification_interval   480
        notification_period     24x7
        notification_options    d,u,r
        }

unix-host is used in many other hosts without a problem, and webwork
host entry was a copy/paste based on other working entries.  I don't see what
could be wrong other than getting the IP right.

I can ping webwork from the nagios monitoring system.

I can't see the problem.
