    Hello everyone! I’v been running into a little bit of trouble attempting to setup nsclient. Ill give you a little background info so you are a little familiar with my situation.

    I have a ubuntu server box running nagios (
    and a 32bit windows 7 box running nsclient (
    Both are VMs.

    I started by downloading the NSclient 3.8 Win32.msi and went through the install process fine.
    During the install I put the allowed hosts as and left the NSclient password field blank and checked the common check plugins, nsclient server, (check_nt), and Enable NPRE server (check_npre) boxes.

    Before starting the service I modify the NSC.ini file as followed:

    commented out the CheckWMI.dll and RemoteConfiguration.dll by adding a # after the;
    for password I put:
    for allowed host addresses I put
    for use_file I put

    (I made the above changes because I was also following:

    I then go to the nsclient service, go to the log on tab and check the ‘Allow service to interact with desktop’ box

    I then go to C:\program files\NSclient and click the nsclient.exe and then nstray.exe

    when I click on the systray exe windows will either give me a failure prompt and close the applicaiton or the service wont start. the systray log is as follows

    I apologize if this problem has been posted before. Thank you for your time!

    SYstem tray is not really supported to be honest. I will try to fix that at some point but since it doesn’t add anything it has a pretty low priority for me…
