Hello McVitas,

Looks like you have a problem with creating a profile of user nx.
There are 2 possible reason:

1. Do you use domain users/LDAP/ActiveDirectory? Do you have non
standard restrictions for users?

2. It’s possible that default user profile on your host might be
corrupted. You can try to create few user accounts and check if
it’s possible to login on their desktops. If you experience any
problems, please refer to this Stack Overflow thread:

Hello,
Your license files look ok. You shouldn’t have problems during the update. To be sure that everything will be right after the update, you can check expiration dates:

sudo grep Expiry: /usr/NX/etc/*lic

Hi,

In log files you have a line:

NX> 701 Running: '/etc/NX/nxnode' --validate.

I was able to reproduce it only when:
– I don’t have /usr/NX/etc/node.lic,
– but I have /usr/NX/etc/node.lic.sample.

I haven’t reproduced a situation with disappearing server.lic. Probably there is also something wrong
with your file. Maybe node.lic and server.lic were from different NoMachine products(?)

Before update, your /usr/NX/etc/ lic files should look like this:

$ ls -l /usr/NX/etc/*lic*
-r-------- 1 nx   root 885 mar 31 18:35 /usr/NX/etc/node.lic
-r-------- 1 root root 894 mar 31 18:35 /usr/NX/etc/node.lic.backup
-r-------- 1 nx   root 817 mar 31 18:34 /usr/NX/etc/server.lic
-r-------- 1 root root 823 mar 31 18:34 /usr/NX/etc/server.lic.backup

$ sudo grep "Product Id:" /usr/NX/etc/*lic*
/usr/NX/etc/node.lic:Product Id:            LEDSN
/usr/NX/etc/node.lic.backup:Product Id:             LEDEN
/usr/NX/etc/server.lic:Product Id:            LEDS
/usr/NX/etc/server.lic.backup:Product Id:             LEDE

There could be missing *lic.backup files if you didn’t use nxplayer’s GUI for replacing licenses.

Hello Vragosta,

We weren’t able to reproduce the error.

Could you gather logs from the affected host:

$ sudo tar cvfz NoMachine-log.tar.gz /usr/NX/var/log

and send to forum[at]nomachine[dot]com please?

Hello @jurgen,
As I understand you installed NoMachine on your custom Linux distro build by Yocto. Now the main problem with the installation is missing HOME dir of user nx:

/var/NX/nx

You can:
1. Uninstall NoMachine:

$sudo /usr/NX/scripts/setup/nxserver --uninstall
$sudo rm -rf /usr/NX

2. Create the dir:

$sudo mkdir -p /var/NX/nx

3. Install NoMachine again in the same way

$/usr/NX/nxserver --install debian

If it doesn’t work you can try to install NoMachine by choosing different sysetm:

nxserver –install {SYSTEM}

SYSTEM:

redhat       Red Hat Enterprise 4 and later.
suse         SLED 10 and later, SLES 10 and later, Open SUSE 10 and later.
slackware
mandriva     Mandriva 2009 and later.
debian       Debian 4.0 and later.
Ubuntu 8.04 and later.
fedora       Fedora 10 and later.

[zaq]

You should get an output like:

“The command completed successfully.”

Looks like something is wrong with creating user accounts on your system.

Could you check if user nx is present in a list of all of your users:

net user

if there is an nx user, please remove it by:

net user nx /DEL

We need to check system logs related to user management. You can enable it by:

1. Click ‘Start’.
2. Find Administrative Tools
3. Open Local Security Policy
4. Go to Audit Policy
6. Enable AuditAccountManagement for Success and Failure:

Click right button of the mouse on ‘Audit account management, go to Properties -> Audit these attempts,
enable Success and Failure.

After that you can check the logs:

1. Go back to Administrative Tools.
2. Open Event Viewer
3. Go to: Windows Logs -> Security
4. Create again the account:

net user nx "YOUR_PASSWORD" /y /ADD

5. In Event Viewer window click Action->Refresh, check logs related to creating user nx account, They have
‘User Account Management’ type in Task Category column.

After that, you can disable system logs related to user management by restoring to original values AuditAccountManagement Policy.

[zaq]

Logs received. Thanks. The problem is directly related to this command:

net user nx “PASSWORD” /y /ADD

Could you:

1) Open cmd as Administrator – open Menu Start and just write cmd, then choose ‘Run as administrator’.

2) Run this command:

net user nx "YOUR_PASSWORD" /y /ADD

3) Send the whole output from the command to forum[at]nomachine[dot]com please?

[zaq]

NoMachine server software needs nx user for its proper working. You can find more information here:

https://knowledgebase.nomachine.com/AR01N00871

If you just need to connect from the Windows machine to another computer you can install nomachine-enterprise-client package. It doesn’t need nx user:

https://www.nomachine.com/download/download&id=16

To investigate the problem please pack a folder with logs:

C:\ProgramData\NoMachine\var\log

and send to forum[at]nomachine[dot]com.

Hi,

We weren’t able to reproduce the error. Could you check your NoMachine
Service shortcut? It’s the path:

C:\ProgramData\Microsoft\Windows\Start
Menu\Programs\NoMachine\NoMachine Service

and check target like you can see in the attached picture.

Also logs will be helpful, please gather them like it is described in:

https://www.nomachine.com/DT10O00163#1.4

and send log archive to:

forum[at]nomachine[dot]com

Hello Babok,

Did you do update by installing *exe file with new version or by clicking in Settings in GUI? Which was your previous version?

[zaq]

Hello,

Could you check status of nxserver start mode:

/etc/NX/nxserver --startmode

if you get:

NX> 807 Service NoMachine status is: Manual

please set as automatic:

sudo /etc/NX/nxserver --startmode automatic
