Discovery on LAN not working correctly

[phirephoto]

Hi,

I have a few computers on my network – all Windows  – and it seems to be hit or miss as to if discovery works. Disabled firewall, everything seems to be the same settings. But if I do discover computers on some of the computers on the network, it doesn’t find any. If I manually add a machine by name, that works fine. Any suggestions on what to look for – ie what port to make sure is opened, etc?

Hello,

1 Please ensure that all machines are on the same network and that mDNS broadcasting is not blocked by a router or by having the machines on different subnets.

2 Verify that on the machines where other servers are not visible in NXPlayer, the option Player Settings -> Security -> 'Don't show other computers on this LAN' is not checked.

If steps 1 and 2 do not help, please proceed:

3 On a machine where other servers are visible and on a machine where the issue occurs (servers are not visible), please run the following commands in the CMD on both machines:

3.1 Check if the %HOME% environment variable is set by running:

echo %HOME%

If it’s not set, you can set it with the following command:

set HOME=C:\Users\YourUsername

Note: Replace YourUsername with your actual username.

3.2 Execute the nxlocate -s command:

"C:\Program Files\NoMachine\bin\nxlocate.exe" -s

Note: The path may be different depending on where NoMachine was installed.

You should see a similar output:

C:\>"c:\Program Files\NoMachine\bin\nxlocate.exe" -s
19308 8516 2024-06-03 17:46:32 022.453 Features/Features: WARNING! Can't open version file 'C:\Program Files (x86)\NoMachine\etc\version'.
19308 8516 2024-06-03 17:46:32 022.453 Features/Features: WARNING! Error is 2, 'No such file or directory'.

19308 8516 2024-06-03 17:46:32 022.453 LocateMain: Running locate application.

After this, type the following command and press Enter:

command=list,type=local

Wait at least 1 minute and then collect the output. During this time, all servers should show up as a response in CMD.
After at least 1 minute, please break by pressing Ctrl + C and send us the output.

Send it directly to forum[at]nomachine[dot]com.

Repeat the above steps on both machines where it works and where it doesn’t.
