Hello all.

Hopefully someone out there can help me.
Has anyone managed to compile the check_nt program under Windows? If so,
can you send me a copy of the binary or (preferably) the modified source
code?
We have a server that is hidden behind another server, and so to monitor it,
I hope to use NRPE_NT on

A quick test to make sure that the port is open is to telnet to it.
telnet YourHostname 1248
On www.nagiosexchange.org you can download my checkagent utility, which will
probe a remote host for various agents (NRPE, NRPE/SSL, pNSclient (including
NC_Net, NSClient++),
If you are using the UCD SNMP daemon (the one shipped
with Linux, but you can compile it for other UNIXes) then this allows you to
monitor for instances of a process.
