You can only run a few rdp sessions at the same time in Remote Desktop Manager and you want to know how to be able to open more sessions.
The amount of consumed memory is dictated by the remote technology, and in the case of RDP, by the Operating System of the remote host.
Windows 8 / Windows Server 2012 sessions do take upwards of 150Mb, whereas the previous versions would consume around half of that.
This is something that we have no control over. You can look for Large Memory Aware Application or use the 64bit edition of Remote Desktop Manager
Rdp session initiation is slow when using Remote Desktop Manager in a virtual environment.
This problem is something that we have also experienced under those conditions (our testing environment is virtual and has minimal memory for each guest).
In the Experience tab of your RDP session, disable everything that is not used. A good method is to select the Modem connection speed, this will disable all settings that are related to appearance.
You can then turn on a single setting to see if it affects the performance negatively. Repeat until you find the combination that works best for you.
You use rdp in embedded mode and the remote session is extremely slow to respond. The session loads fine, but when you get logged-in the remote computer, it becomes unresponsive. Mouse clicks, keyboard presses and application loading are extremely slow. In external mode, everything is running fine.
Disable your Anti-virus and test the connection to see of this make a difference.
If you use Trend Micro Business Security, add RemoteDesktopManager.exe, RemoteDesktopManager64.exe, and Embedded32.exe to the Process Exception List under Preferences – Global Settings and update the Trend client.
If you use Symantec Norton Internet Security, ensure you allow Remote Desktop Manager to access the internet in the Program Rules.
Uncheck all settings in the Local Resources tab.
Check Disable display scaling on high DPI settings in the options.
Download and install Microsoft RDCMan to see if it is related to the RDP ActiveX. Remote Desktop Manager uses the same technology and this will ensure that your workstation does not have configuration issues.
Connections fail for some hosts.
There are known security updates that have broken connectivity to a host, but they have been fixed in ulterior patches. If you keep the hosts updated then it should be something else.
Sometimes the mapping of local devices will cause issues. Uncheck all settings in the Local Resources tab.Feedback
