How to RDP
By default, RDP is configured to collect a username and password before the RDP client connects to the remote computer, so the actual remote login screen is not shown. This feature is called NLA (Network Level Authentication). To use WWPass Winlogon, NLA must be turned off.
To use WWPass Winlogon on a remote computer, disable NLA and configure the RDP connection to always show the remote screen.
Start the Remote Desktop Connection application (mstsc.exe in the command line), enter the remote computer name or IP address, click the "Show Options" button in the lower-left corner, click the "Save As" button, and save the configuration (a text file) with a convenient name, for example, MyRemoteComputer.rdp.
Now open the file in any text editor (for example, Notepad) and add the following line:
enablecredsspsupport:i:0
To disable NLA on the remote computer, open Registry Editor and set the UserAuthentication property value to 0 (disabled) at the following path:
HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
Once NLA is disabled on the remote computer, the full remote login screen will be shown.
