Enable Remote Desktop via cmdlet?

from：http://powershell.org/wp/forums/topic/enable-remote-desktop-via-cmdlet/

Hi,

Server 2012 & PowerShell 3.
I simply want to be able to allow remote desktop connections to a server (as done in the GUI via system properties->Remote Tab->Remote Desktop Options).
I have taken a look at the RemoteDesktop Module but cannot see a cmdlet to achieve this?
Is there one? If not any way to achieve via PowerShell?
Thanks,
Nigel.

You can enable RDP with PowerShell by using the registry psprovider:

# Allow RDP Connections to this computer

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

# Require Network Level Authentication

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

You can use this to allow the firewall exception since you're running PowerShell v3:
# Allow the Remote Desktop firewall exception

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

Since you're using Server 2012 which means PowerShell remoting is enabled, you can throw all of this in the script block of Invoke-Command to remotely enable RDP:

Invoke-Command -ComputerName 'server1', 'server2' -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
