Windows-10: Failed to start nxserver process

[bpowell]

I’m trying to run NX free version 6.7.6 on a Windows-10 system to replace MS Remote Desktop.  The server will not start though.  In the system services, I see “nxservice” is running just fine, but when I try to connect, nxserver can’t be started.  I’ve tried re-installing twice and rebooted after each one.  I’m kind of stumped.

Thanks!

I have also attached the nxdevice.log just in case.

Hello bpowell,

Hello bpowell,

Logs indicate that there’s a problem with obtaining security context of user nx. This might be related to incorrectly installed nxlsa module.

To reinstall nxlsa module:

1. Start cmd as Administrator.
2. Change directory to bin subdirectory of NoMachine installation directory:

‘cd <path_to_nomachine_installation>\bin’

3. Execute:

nxservice64.exe –uninstall nxlsa

4. Restart Windows.
5. Repeat points 1. and 2.
6. Execute:

nxservice64.exe –install nxlsa

7. Restart Windows.

Alternatively you can simply uninstall NoMachine, perform restart, install NoMachine and restart Windows again.
Let us know if you still experience the issue.
