MailBag Friday (#26)

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 currently using a Cisco(LinkSys) WVC80N Wireless Monitoring Camera on our system to look at our production line.  I have added them to ThinManager. However when I connect, I see the webpage that is hosted on the camera, but when I select “View Video,” I get this message:

Security Warning. Do you want to install this software. Name:

if I click install, the video page opens but there is no video feed, just a square with a red “X.” If I click refresh I get a script warning error.  I can see the other pages of the web site.  What do I do?


You need to install their ActiveX or Java app and run as an administrator to see the video feed in the browser in ThinManager.

When the video is sent to a client it is displayed in a video engine provided by the ThinManager.Camera Display Client. You have to provide an administrative account and the display client handles everything else.

To view the video with in ThinManager itself we launch a browser and connect to the camera. Usually this requires the installation of an ActiveX or Java program contained on the camera to be the container for the video feed. You have to be an administrator to run it.



I have recently set up a new Win Server 2008 R2 Terminal server but I am getting the following error:

“Access is denied.  This initial program can not be started.”

The application I am trying to run is Internet explorer (C:\Program Files (x86)\Internet Explorer\iexplore.exe). I have logged on as the user and I can run this manually, can you suggest what might me the problem?


You will need to whitelist IE in the Remote App Manager:

Start > Administrative Tools > Remote Desktop Settings > RemoteApp Manager

From here you may either allow all applications to be started: RD Session Host Server Settings > Change > Allow users to start both listed and unlisted programs on initial connection.


You may add IE to your whitelisted programs by clicking “Add RemoteApp Programs” on the right.



Our current application has 144 screens and we want to use iTMC with an iPad that will be connecting via 3G to monitor sessions. Will this affect the speed of seeing the screens and any effect regarding the data size being exchanged?

It depends. The bandwidth used by iTMC is the same as the bandwidth used by RDP Protocol. This bandwidth can vary a lot depending on what applications you are running, the size of the screen, color depth, and other factors.

Here’s a few posts regarding this question …

With that being said, we have never encountered an issue with low bandwidth while using iTMC.



Do you have any update on when “Terminal Shadow” display clients will be available in iTMC? We have an immediate need for this feature if it is currently available.


If you are looking to shadow a specific terminal, I suggest using ThinManager Mobile which has the ability to shadow terminals:
