    NoMachine can’t accept Microsoft account ?

    Hello hastur18,

    NoMachine authentication on Windows supports local account names and domain account names only. This means that you need to check the local account name of Microsoft account which you attempt to use, on remote machine.

    In order to do so:

    1. Log on to desktop of machine you want to use, using Microsoft account.
    2. Click on the search icon right to the start Microsoft icon.
    3. Type ‘cmd’ and press enter.
    4. Inspect path displayed in console, the last part should denote the user name,
    it should be something like:



    Hello Cato,

    I have tried this solution, but I have this message :

    La négociation de session a échoué.

    Hello hastur18.

    Unfortunately we cannot help here without the logs from server side.
    You can find instructions about debug and collecting logs here:

    Please enable the logs in server.cfg and node.cfg, then just to be sure we have everything
    covered restart the NoMachine server: You can do it from NoMachine Monitor GUI. Then please
    repeat the connection and send the logs to forum[at]nomachine[dot]com referring post topic in mail subject.
