Legacy SSrdpManager requires the server to disable Network Level Authentication (NLA).


To disable NLA on Windows Server 2012 and 2016:

  1. Open the Control Panel. Ensure that the control panel is showing items by Category (i.e. not in Classic View). Click on System and Security and under System Properties > Remote tab select Allow remote connections to this computer.  
  2. Uncheck Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended).
  3. Click Apply and OK.
