i forgot to mention that this client was installed when i was testing nagiosxi. I just added the new nagios core server in the "allowed hosts" in the nagios agent on ia0cw007. Do you think i need to do a re-install with only nagios core server.
I have added firewalls rule attachment. pls suggest how to proceed.

Can you try the telnet command replacing host name with ip address?
Code: Select all
telnet ipaddress 5666
ping ipaddress
And post result.
Are your check commands working in the Core web gui now?

Try this from a command line on your Nagios server:
Code: Select all
/usr/local/nagios/libexec/check_nrpe -H 10.52.94.31
Also, look through this guide and make sure you followed all of the necessary steps to enable nrpe on your Windows box.

Thank you, it worked.
Can you leave this open for 2 days more. I would try adding 2 more hosts and would post updates.
