    Description

    Hello,
    i’ve got a question : On a windows 10 computer i’ve got around every minutes this error message : NetJoin event id 4097.
    It seeems that it’s corresponding with the fog client which test if computer is already joined to domain : HostnameChanger attempting to join domain.
    Is there a way to avoid this ?

    Thanks for your help

      • Is the system configured in FOG to join the domain?
      • Are the credentials set in FOG for domain joining correct?
      • Do other Windows 10 systems throw this error?
      • Do Windows 7 or 8 or 8.1 systems throw this error?
      • Can you copy/paste the complete error message from Windows Event viewer please? We don’t want a screen shot, We want text.

          @plegrand I don’t know the fog-client stuff well enough but looking at the code it seems like this is intended. Every time the HostnameChanger module is called it checks the hostname and tries to join the domain if hostname is correct.

          Though I am not sure how often the HostnameChanger module is meant to be executed. @joe-schmitt or maybe @Tom-Elliott can surely give a better answer to this question.

          Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

            @Sebastian-Roth You are correct.

            @plegrand It is checking every cycle. This is so that if there is a change it will happen the next time the client runs its checks. Is there some worry in regards to the client performing this every check?

              @Tom-Elliott Not really. It’s only because windows see it as an error

                @plegrand I just stumbled upon the FOG_ENFORCE_HOST_CHANGES setting in the FOG web UI and remembered your post:

                This setting only operates with the new client. Default value is 1 which allows the new client to enforce name changing on every cycle it checks in, so any change on FOG will take place on the next cycle. If unset (value 0) it will only perform hostname change and/or AD Joining on host restart.

                You might want to give this a try to get rid of the messages.

                Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)
