nagios2: failover

Hello Nagios Users,

I'm attempting to setup a second nagios server up to do failover monitoring
in case my primary nagios server goes down.

Running into a odd problem in talking to the nrpe daemon on the master
server.....

When I run the following cmd prompt, nrpe does not allow me to connect from
the new host even though it is specified in the master nagios server
nrpe.cfg file.

SLAVE$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.41 -c check_load
Connection refused by host

However, when i run the same cmd for another host, it returns successfully.

SLAVE:~$ /usr/lib/nagios/plugins/check_nrpe -H 10.10.10.43 -c check_load
OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0;
load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0;

**Note thta the IP for the nagios failover server IS listed in the nrpe.cfg
allowed_hosts directive and the nrpe daemon has been restarted.

Any insight on this issue? I am running Nagios 2.11.

Thanks,
JJ
