Creating a remote session to a device is simple once all pre-requisites are met.
We will create a new session whenever we need remote access to an endpoint. Typically this is done in response to a service call from a customer in the field.
From any device in the admin console that meets pre-requisites (web and native shown below), you can choose to open a Remote Session from the context menu. Note that the admin user must have rights, and the client itself must have reported the right "state" to be controlled. macOS and Windows clients will be the only ones to show Don't Prompt User but that will only appear if the FileWave client has been set to allow remote control and to allow unattended remote control to see both options. The original Observe client permissions are how TeamViewer permissions are being controlled for macOS and Windows. If you would like to change a client's permissions then a Superpref can change these settings.
The admin workstation must be a Windows or Mac device to begin a TeamViewer session. The admin workstation will open a browser tab to get.teamviewer.com that will in turn prompt to launch the installed TeamViewer app in order to connect to the remote system. Depending on your browser settings, you may have to modify allowing pop-ups to see the page open.
Note that you can save your setting for this so that it doesn't prompt the next time. We'll choose to launch the installed version and then the TeamViewer App itself will launch this page:
This window will remain open, waiting for the remote user to accept the session. If they begin the session, you will be redirected to the remote session. If no response is sent, the session will time out.
