2000 server


hello world, I have some problems about nrpe.
I always used the installation mode for nrpe with nrpe_nt.exe -i form cmd.
now i want to use nrpe with a windows 2000 server.
I modified the nrpe.cfg but after restarting/reinstalling nrpe_nt.exe, it seems that the nrpe.cfg wasn’t modified.
how can I do to make this changes active?
Thanks to all.
