[Nagiosplug-help] Where to pass check_nrpe args in Nagios config?

[Curt Shaffer]

I am having something along these lines as well. I have 1 Windows host
running the nrpe_nt daemon and I am trying to run a command from the
nagios box like this:

./check_nrpe -H (Windows running NRPE) -c wmi_disk\!(host to be
executed on)\!C:\!80\!90


Now this same command works for my Windows host running NRPE if I do
it like this:

./check_nrpe -H (Windows running NRPE) -c wmi_disk\!(Windows running
NRPE)\!C:\!80\!90


But it does not work to other hosts on that network. I have tried to
run the command from the Windows running NRPE directly to the other
hosts and it script returns the proper values, it seems that it is
just not getting back to nagios. I get Error! on the nagios host in
response to that command. When I echo the output on the nagios web
interface it looks like it is sending the proper command just an
Error! in response.
