SCCM Remote Desktop capabilities

Hi David,

I have answered the questions below, but I want to also clarify that System Center Configuration Manager is a much bigger tool than just Remote control and in fact remote control just happens to be a feature in there to help assist with the over all management of your enterprise devices including Windows Updates, Office 365 updates and management, Windows 10 Current Branch/Current Branch for Business, software distribution, VPN profiles, Antivirus and Antimalware, operating system deployment, configuration management, compliance settings, and much more. Like wise Configuration manager is only one part of a much larger Data Center Management suite that offers so much more.

To answer you questions:

1. Remote access to local network devices (I've seen this work from clips online)
   Yes, you can access devices that are on your local LAN/WAN as long as the proper ports are open between endpoints.
2. Remote access to remote worker devices. (Devices connected to the domain / Azure AD, but not on the local network):
   If the device has VPN Direct Access, then it is possible, of course this depends on firewall ports, VPN policies, and such factors. If it is strictly an internet based device, then unfortunately it is currently not available, however Skype for Business may be an option in these situations.
3. When I'm accessing remote devices as the administrator, I need UAC access to install applications. Does Remote Control support UAC prompt window? 
   Yes, you have the ability to support UAC prompts with Remote Control.
