Enabling Remote Desktop with Group Policy

If you want to enable a computer as a Remote Desktop server (i.e. allow remote connections to it) via Group Policy, you need to set two options, both under Computer Configuration:

• Administrative Templates → Windows Components → Remote Desktop Services → Remote Desktop Session Host → Connections → Allow users to connect remotely by using Remote Desktop Services (set to Enabled)
• Administrative Templates → Network → Network Connections → Windows Firewall → (a profile) → Windows Firewall: Allow inbound Remote Desktop exceptions (set to Enabled)

Once those two items are enabled, the affected machines will allow users to connect remotely.
