Is it a virtual server?
I had got the same issue once, when I used Nagios running on a VmWare machine.
As soon as I migrated it to HyperV, everything started working.

Well, I wouldn't put it on the hypervisor right away, that's not a terribly common problem. Let's start by making sure those ports opened up with the previous changes.

Alright, so it looks like currently the port used by check_nt is closed, while the NRPE port "5666" is open, do you have networking equipment in the route to the windows server, or the servers that are displaying this? Did you check the windows firewall?

So for working alright. But from last couple of days I am facing this issue.
Windows firewall is off.

Can you post your nsclient config in code wraps?

Something is very strange here. Is 172.16.98.129 your windows server? I ask because port 5666 was open while 12489 was not in your previous nmap, but your nsclient config is not configured for nrpe(5666), but is for check_nt(12489). Are you sure this is the file from the windows system and that the the windows ip is 172.16.98.129?

172.16.98.129 is (Nagios Server)
However, I have changed this to 192.168.
