are you sure nrpe is running on the client machine and that selinux is turned disabled

echo 0 > /selinux/enforce

will turn off selinux on the client machine

Does NRPE run on the server you want to monitor.

ps -ef | grep xinetd

Could you check with netstat if a process listens on port 5666 on the server you want to monitor?
Show the output of:

netstat -tulpn | grep 5666

Can you telnet to port 5666 from the nagios server to the server you want to monitor?

telnet <IP address server> 5666

Is iptables (or other firewall) opened?

Can you post your /etc/xinetd.d/nrpe file here for us to review?
