NSClient++ Help (#1) - Config issue (#941) - Message List

Hello, nsclient is great but I'm having some issues with the new config in 4.0-32bit. After trying to run all the checks that used to work in the old version I just get "No data was received from host!" in Nagios now. I did some digging but I'm kind of stuck. Any help would be much appreciated.

The service is running and listening on my Windows box and I can even open a connection from the Nagios server with "telnet 1.2.3.4 12489"

The trouble starts when trying to use check_nt.

./check_nt -H 1.2.3.4 -p 12489 -s PassWord -v CLIENTVERSION
No data was received from host!
could not fetch information from server

I turned logging up to 'debug' level in the config but nothing shows up.

Thanks
