Q: We have over thousand outside clients need to access our RD server. Does Microsoft offer any External clients license for those clients access our RD Servers?
A: Yes, you can purchase RD External Connections license. Quoted from Microsoft: “An external user is a person who does not have employee-level access to your company’s network or the network of your affiliates, and is not someone to whom you provide hosted services. An EC license assigned to a server permits access by any number of external users, as long as that access is for the benefit of the licensee and not the external user. Each physical server that external users access requires only one EC license regardless of the number of software instances running. An “instance” is an installed copy of software”.
