Terminal Service Plus

I have one client who cannot connect to one of our 2 tsplus servers either with RDP or web.

Client receives standard windows RDP cannot connect because... message.
Last connection about 3 days ago, they have been connecting for about a year.
All other clients from other location connect successfully.
Client still connects to our other tsplus server successfully.
It looks like their IP address is blocked on the one server.
But there no entry in the tsplus advanced security blocked IP addresses.
There is no entry in windows 10 defender firewall inbound blocking entry.
Created new windows firewall inbound entry to allow their IP address, still no connection.
When client tries to connect, there is no entry listed in the tsplus advanced security log.
All tsplus products are on current versions.
Originally was using windows firewall
Now using tsplus firewall


WindowS 10 Pro 1903
tsplus (current version, 5 users)
tsplus advanced security basic (current version)

Thanks, Alan

Also, if I turn off the firewall the client can connect successfully.

Hello,

Make sure you did not install TSplus on a Windows 10 Home edition as it is not supported. You will have to either revert to previous version of Windows or upgrade to Windows 10 Pro.
If you installed TSplus on a server version of Windows, check that the RDS role is not installed, if that is the case, uninstall this role and reboot. Then reapply the latest update of TSplus and reboot again.

Your server should be accessible using either port 80/443/3389 depending on your connection method. You can try to connect from the console of the server by launching a mstsc.exe with 127.0.0.2 in the address. If you can connect from the console but not from a remote location please check your router / firewalls to allow traffic.

If your system has connection issues and the above did not work, you will need to check the following :

- Process one reboot to verify if you the issue remains after restarting the system.

- Verify that your TSplus release is not a too old one.
For old release (5.xx and below) the TSplus technology cannot match with the latest version of Windows.

In such case, the solution is to update to the current release of TSplus.

- In case of incompatible Updates that has been installed on your system, the solution is to download and run the latest update on your server : https://dl-files.com/UpdateRelease.exe
If you cannot update, use this procedure to update only the core of TSplus :
- on the server, open a DOS command prompt with Administrator Rights
- enter the command :
'cd c:\program files (x86)\tsplus\userdesktop\files'
- enter the command :
'svcac.exe /updatekernel' and wait a few seconds for the popup to indicate that the kernel has been updated
- Open the Windows Service Manager and restart the Application Publishing Service (APS). Confirm the restart of the two dependent services.

- With the AdminTool, verify the status of your TSplus license.
It is important to know if your issue is related to a TSplus license or to a Windows system problem.

If your current TSplus license is invalid you will need to install the latest TSplus update and activate a new valid one.

Open a windows explorer and locate the license.lic file in the following path C:\Program Files (x86)\TSplus\UserDesktop\files and apply your license again.

- If the above does not correspond to your issue, open a services.msc and make sure the "Application publishing service (APS) is running as well as the Remote Desktop Service. If the service is not running then it means another application is conflicting TSplus like skype or teamviewer. You may need to change TSplus port to another one that would be free to use.
