We need a LOT more information.

At a minimum send us your service definition. If you've customized your command definition we'll want that also. If you're using nsclient - what version and you may wish to send us your nsc.ini or nsclient.ini. Obfuscate any passwords that you send us.

Probably isn't hurting anything, but can't hurt to fix the spelling:

Thank you for the quick reaction.
I have done what you have said but now i am getting:

CPU load WARNING 2015-04-09 07:23:14 0d0h4m52s 4/4 could not fetch information from server

Also in the nsclient log he is saying now:
Rejected connection from: 10.10.0.193

In your nsclient.ini file on your windows system, edit it and change the following from

Code: Select all

allowed_hosts =10.10.0.193
to

Code: Select all

allowed hosts = 10.10.0.193
Save the file out and restart the nscliect++ service.

The underscore in the names are for the old version of Nsclient++, the new versions doesn't use them.

i have done the change but it looks like the service is flapping between OK and could not fetch information from server

#edit#

i added an other windows server this one is doing perfect. I really want to thank both of you for all your help.
