In order to fix the above issue we need to disable NLA authentication which is not recommended.

A fork of node-rdp which is node-rdpjs2 at: https://github.com/Siyer2/node-rdpjs also throws the same error. However node-rdpjs even though nla authentication is enabled, is not working or probably taking too long to connect.

Error: by node-rdpjs-2,

To disable NLA authentication, run:

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" /v UserAuthentication /t REG_DWORD /d 0 /f
