You haven't really provided enough information.

I've seen issues with this to a variety of reasons including misconfigured NSC.ini on the windows client, firewall blocking the port from Nagios master on the windows client, incorrect entries on the Nagios server etc...

For troubleshooting I'd suggest:
1) First verify your host is resolving the client IP correctly from Nagios master:
host <client>
Verify that the IP returned is the same one you defined for the client in hosts.cfg.

2) On the Nagios master from command line attempt to connect to the port on the windows client to verify you can. This will help you determine if issue is networking/firewall - often folks turn on the Windows firewall and forget to open up the port.
e.g. of you're using nsclient++ in NRPE mode and standard port then try "telnet <client> 5666".

3) From command line on the Nagios master attempt the command to the client.
e.g./usr/local/nagios/libexec/check_nrpe -H <client> -p 5666 -c CheckCPU -a warn=85 crit=90 time=30
This will help you see if the command you think is running is working and bypass all the the rest of the Nagios setup. If it works then you know your issue is the Nagios configuration - if it doesn't then it is likely something on the client side.

4) Review the NSClient++ log on the client. Usually it gives rather good indications as to where the issue is so long as networking/firewall allowed the master to talk to the client.

Failing all that you'd need to provide your NSC.ini, your hosts.cfg for this client, your services.cfg for this client and your commands.cfg for the commands used for this client for anyone to intelligently tell you what issues you might have.

sanitize (the IPs?) and post the contents of the nsclient.ini please.
