Ajuda - Monitorar Servidor Windows

Pessoal,
 Estou com problemas para monitorar servidores Windows, eu instalei o
NRPE_NT nas máquinas normalmente

nrpe_nt -c nrpe.cfg -i

startei
net start nrpe_nt

Ele tá rodando, inclusive quando eu checo do Nagios ele responde:
NRPE_NT v0.8b/2.0

Eu instalei o
WMI agentless plugins
para instalar em apenas um servidor o NRPE, quando eu rodo o comando
/check_nrpe -H 10.0.102.246 -c show_properties -a
127.0.0.1Win32_PerfRawData_PerfOS_Memory

Dá o erro
CHECK_NRPE: Received 0 bytes from daemon.  Check the remote server logs for
error messages.

Nos logs do NRPE
2008-07-01 10:36:03; 3976; 4;Error: Request contained command arguments, but
argument option is not enabled!
2008-07-01 10:36:03; 3976; 4;Client request was invalid, bailing out...

o estranho que tá definido no nrpe.cfg (do Cliente Windows)
command[show_properties]=cscript.exe //nologo //T:60
c:\nrpe_nt\plugins\v2\get_counter_type.vbs "$ARG1$" "$ARG2$"

Eu defini no command.cfg do Nagios

define command {
  command_name show_properties
  command_line $USER1$/check_nrpe -H 10.0.102.246 -c show_properties -a
$HOSTADDRESS$ $ARG1$ $ARG2$ $USER9$
}

Alguém pode me ajudar?

Vlws :)
