NRPE_NT vs. NSClient

The Port issue is right...but hell, you don't have to reboot your server
just because you
Did some changes to the nsclient port! I wrote a simple cmd file which
runs before the setup routine of
Nsclient, and whic automatically adds the new port number and a password
to the reg.

The problem with the ports in use mostly appears when you're running
exchange server on your server. The exchange server simply graps ports
greater 1024 in default settings...

I've tried some w2k3server boxes, runs fine here.


To the question asked before:

I mostly run NSClient + Eventlog Agent on all windows servers, just
because it's no big administrative overhead. With nrpe_nt you have to
care for config files on each server, and have to do a lot of changes on
each server.
Though NRPE_NT is really nice when you have to do things with Event
Handlers or wmi scripting and stuff...
