Nagios Error: Could not find any host matching/Could not expand hostgroups and/or hosts

> Error: Could not find any host matching 'win4503'

Nagios has found an object which refers to a host called win4503, but
can't find a host definition for it anywhere in your configuration
files.

> Error: Could not expand hostgroups and/or hosts specified in service (config
> file '/usr/local/nagios/etc/windows.cfg', starting on line 36)

This tells you where  Nagios found this problem.

It looks like you have defined a service in your windows.cfg file, but
have not created a host definition for host "win4503'.  Have a look
through the sample configuration files to see what a host definition
should look like, or see
http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host

An excellent way to get started with Nagios is to read the book
"Nagios" by Wolfgang Barth.  http://nostarch.com/nagios_2e.htm

hth,

Jim
