I have created Nagios virtual Instance on Amazon Ec2 Cloud enviorment according to steps given below URL:
https://assets.nagios.com/downloads/nag ... -Cloud.pdf
After that I have Installed NSClient++ on windows Server the one which I have to monitor using Nagios EC2 Instance but its showing Socket Time out error for all monitored services in NagiosXI dashboard[ Note: Firewall turned off on windows server so there is no chance to block ports]

In the Amazon management interface you need to open the network ports for it to work.

Is this on the windows server in the EC2 instance?
Can you provide your nsclient.ini file from the Windows server.

Hi,
Just to give more info, I have open TCP ports on Nagios EC2 Instance to communicate with our local windows server(Note:This windows server is running locally in my company and only Nagios Instance running on Amazon AWS)
Also please find attached nsclient.ini file from the Windows server.

I don't see any listening ports in your config, what is the output of netstat -an | findstr "5666" on the windows machine?
Also - have you enabled the rules through Windows firewall?

Here is the output of netstat -an | findstr "5666"(Refer attached screenshot).
Also my windows firewall turned-off , Do we still require to enable the rule through windows firewall.

Can you also run netstat -an | findstr "12489"?
Are your services attempting to use check_nrpe or check_nt?

I'm not sure which one(check_nrpe,check_nt) my service attempting to use, Can you give some steps to check this?

Looks good regarding listening, I don't think your nsclient configuration is an issue.
To figure out what service you're using navigate to Configure -> Core Config Manager -> Click 'Services' on the left side, and search for the service in question.
You should see a page similar to this -

One more thing to check, from the nagios machine, on the CLI can you run
nmap windowsip? (replace windowsip with the IP for the windows machine we're trying to check)
