whats is procedure for install nsclient for windows server 2012 and this ok operate?

Is the server running Windows Firewall? If so, you will need to make sure port 12489 is open to the remote Nagios machine. I would also make sure there aren't any firewalls on your network filtering/blocking that port.

I would also ensure that your Nagios machine was added to the list of "allowed hosts" when you ran the installer wizard.

hello!

Thanks for response. Firewall is disable (image):



and my nsclient.ini is this (without pass for connect and nagios server allowed is all):

thank you very much for your Help !!

The allowed hosts option needs to be setup in the nsclient.ini file for the agent to run. It is required.
Edit your nsc.ini file and put the following in it. Then restart the NSClient service and see if that works for you. Replace xxx.xxx.xxx.xxx with the IP address on the Nagios server.

allowed hosts = xxx.xxx.xxx.xxx
