check_nt - error

Hi everyone,

I recently installed nagios3 on my ubuntu 12.04.1 LTS.

So far i am able to see the windows host i want to monitor , i also see the service i want, which is c:\ Drive space, however when i get the notifications by emails , here is what i see

Service: C:\ Drive Space
Host: server
Address: 192.168.2.100
State: UNKNOWN

Date/Time: Wed Nov 14 08:59:06 EST 2012

Additional Info:

missing -l parameters

I will paste a copy on my nagios.cfg. Also please note, that when running sudo nagios3 -v /etc/nagios3/nagios.cfg, i get no errors and no warnings.

Can you please help?

Thanks in advance

Windows.cfg
