Enable Remote Desktop Using PowerShell

Enable Remote Desktop Using PowerShell

Open an elevated Windows PowerShell session and run the following commands. This first one creates the fDenyTSConnections value and sets it to 0 (off). This makes sense, because we don’t want to deny Terminal Services (TS) connections.

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server' 
-Name fDenyTSConnections -Value 0

Set Network Level Authentication for Remote Desktop

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\
WinStations\RDP-Tcp'-Name UserAuthentication -Value 1

Setting Firewall Rules :

Set-NetFirewallRule -DisplayGroup 'Remote Desktop' -Enabled True

Since you’re using Server 2012 which means PowerShell remoting is enabled.

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server' 
-Name fDenyTSConnections -Value 0

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal 
Server\WinStations\RDP-Tcp' -Name UserAuthentication -Value 1

Set-NetFirewallRule -DisplayGroup 'Remote Desktop' -Enabled True

you can throw all of this in the script block of Invoke-Command to remotely enable RDP

Invoke-Command -ComputerName ThatLazySRV01 -ScriptBlock {
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server' 
-Name fDenyTSConnections -Value 0
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp' 
-Name UserAuthentication -Value 1
Set-NetFirewallRule -DisplayGroup 'Remote Desktop' -Enabled True
}
