Windows Remote Desktop Services External Connector

Network access from your business partners or customers to your Windows Server can be aquired through Windows CALs or external connector for each of your external users. A Windows Server External Connector (EC) licenses for each server will grant your external users access to this server.
An external user is a person who is not an employee, or similar personnel of the company or its affiliates, and is not someone to whom you provide hosted services using the server software. An EC license can be acquired for servers running Windows Server Standard, Enterprise, and Datacenter.
