MailBag Friday (#48)

Every Friday, we dedicate this space to sharing solutions for some of the most frequently asked questions posed to our ThinManager Technical Support team.  This weekly feature will help educate ThinManager Platform users and provide them with answers to questions they may have about licenses, installation, integration, deployment, upgrades, maintenance, and daily operation.  Great technical support is an essential part of the ThinManager Platform, and we are constantly striving to make your environment as productive and efficient as possible.


I am trying to set up a Redundant Pair of ThinManager Servers. But I got an error stating “Synchronization failed” when I was finishing the process. Can I redo it again ? Where can I see the Synchronization status?

The Synchronization tab will show you your Synchronization Status. If you have Auto-Sync setup, ThinManager will automatically attempt to re-sync with it’s peer.  You also need to assign multiple terminal servers to a display client for fail over to work. Once the session is unreachable on the terminal server, the clients will failover.

Don’t forget to reboot the Terminal after you make the change.




I have ThinManager v3.1 installed on my terminal server. I recently added an Advantech UNO-1150 client and got a message that ThinManager couldn’t recognize it. Your Compatibility List shows it as a recognizable device.  Please advise.

Most likely the UNO-1150 hadn’t been added to the TermCap as of version 3.1. The 1150 is supported in ThinManager 6.0 SP4 – our latest release.




I am having a type of a memory spike. When we activated a terminal by it self running a deployed app, the memory spiked to an insanely high value and stayed there. Any idea why this would happen?

When a Terminal establishes a session on a Terminal Server, it launches the application(s) you specified as Display Clients. The launching of an application would cause a spike in system resources like what you saw. The only overhead from the ThinManager perspective is keeping an RDP session open.

Clicking the “Resource Monitor” button will launch the Windows Resource Monitor which should give you more information about what is taking up resources.





A colleague, has created a Master License and added the product license for a temporary virtualised installation of ThinManager at one of our sites.  I am in the process of building the servers that this license was purchased for and need help re-assigning the license to the target installation. How can I change the Installation IDs associated with this license to match the true installation IDs on the target servers?

You can reactivate the Master License and provide the new Installation IDs. Please see the following link for more details:

For future reference, if you are deploying a test system you can get a free demo code for each system from that will be valid for 30 days.
