reg add "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\WinStations\RDP-Tcp" /v "PortNumber" /t REG_DWORD /d 33899 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\Wds\rdpwd\Tds\tcp" /v "PortNumber" /t REG_DWORD /d 33899 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Terminal Server\WinStations\RDP-Tcp" /v "PortNumber" /t REG_DWORD /d 33899 /f

reg add "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Terminal Server\Wds\rdpwd\Tds\tcp" /v "PortNumber" /t REG_DWORD /d 33899 /f
