Windows 10 user authentication failed over LAN

[fefinde]

Hi folks, thanks for any help in advance.

I’m having a problem where the computers are able to see each other, the connections auto populate in the NoMachine connection list, but I am unable to connect with username in password no matter what I do. I have the connection set as private. I am able to connect over the external IP but not over the local IP in the lan. I have done all the fixes here.

Below is the fix from that link that I tried.

Open Start, type: system information
Hit Enter
Click System summary
Look in the right pane

Copy the system sku info into reply here.

See example: https://imgur.com/qzektpA

Open Start, type: CMD
Right click CMD
Click Run as administrator

At the command prompt, type:

netsh int ip reset

Hit Enter
Exit the prompt then restart

Open Start > Settings > Update & security > Troubleshoot
Scroll down
Click Network adapters
Click Run the Troubleshooter

When complete, restart to see if the problem is resolved.

If not, press Windows key + X
Click Device Manager
Expand Network adapters

Right click your adapter
Click Uninstall

Exit Device Manager, restart. Windows 10 should detect the network adapter then reinstall it. Check if you can connect and browse.

also try:

Open Start > Settings > Network & Internet > Status

Scroll to the bottom then click Network reset.

1. Which NoMachine version are you using?
2. Are you able to ping that machine using IP address?
3. Are you able to ping that machine using hostname?
4. During NoMachine connection are you using IP or hostname?
5. What exact error shows? Can you send a screenshot?
6. Can you send a screenshot of NoMachine processes on the server host? (Ctrl+Shift+Esc, choose “More details” and sort by name).
