Scenario: Your license allows more than 2 users, however Remote Access allows no more than 2 concurrent connections.
1 - Please update Remote Access installation to the latest version, reboot the server and try again.
Make sure no users are logged in before installing this update, you can check for remote users by launching a task manager and clicking on the users tab. Disabling your anti virus is also recommended.
Make a scan exclusion rule on C:\wsession and C:\Program Files (x86)\Bsoft-App\UserDesktop\files and make sure your users have sufficient rights to read and execute all programs in these folders.
2 - If it still doesn't work, then it means that a Windows update has impacted the RDP connection module and has overwritten the Bsoft-App settings.
- open a command prompt as administrator
- navigate to the Bsoft-App\userdesktop\files installation directory (cd "c:\Program Files (x86)\Bsoft-App\UserDesktop\files")
- run 'svcac.exe /updatekernel'
- after the popup, open the Windows Services Manager
- open the Wndows Service Manager
- restart the 'Application Publishing Service (APS)' service. Two services will also be restarted
After that you should return to normal operation in multi-session mode.
