    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: Creating locate client.
    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.
