Description

Use Enable-RDPRemotelyCIM to turn on Remote Desktop across one or more systems via the CIM Win32_TerminalServiceSetting class. The function enables both the service and the firewall exception by calling SetAllowTSConnections with AllowTSConnections=1 and ModifyFirewallException=1 for each computer supplied.

Usage examples

Enable-RDPRemotelyCIM -ComputerName 'host01'
Import-Csv .\servers.csv | Select-Object -ExpandProperty Name | Enable-RDPRemotelyCIM

Run the script from an elevated session that has network access and appropriate permissions to configure the remote hosts.
