a socket timeout means it could not connect the nrpe port.

If you try this

nagios at nagios:/usr/local/nagios/libexec$ ./check_nrpe -H winxp01
I (0.3.2.9 2008-05-17) seem to be doing fine...

so without any commands to be run, it just checks whether the nrpe service
is ok.

If you try a not defined command in nsc.ini, like this:
nagios at nagios:/usr/local/nagios/libexec$ ./check_nrpe -H winxp01 -c test
UNKNOWN: No handler for that command

there is no 'test' command defined, so it gives me an UNKNOWN.

in your nsc.ini check that the NRPEListener.dll is enabled, the [NRPE]
section should look (at least) like this;

[NRPE]

port=5666

command_timeout=60

allow_arguments=1

socket_timeout=30

and your [NRPE Handlers] section should contain your allowed checks (here
only services and disks):

nrpe_CheckService=inject checkServiceState CheckAll exclude=SysmonLog

nrpe_CheckDriveSize=inject CheckDriveSize MinWarn=10% MinCrit=5% CheckAll
FilterType=FIXED FilterType=REMOTE


your nagios server must be allowed to query the nrpe server (check firewall
and allowed_hosts settings in nsc.ini)

your nsclient++ is quite old, you should try a newer one. For quesions about
nsclient++ the proper forum is the one at nsclient.org
