ESA Core and RADIUS on a client operating system (client OS) Installing ESA Core (Authentication Server) and RADIUS Server on a client OS in the list of Supported Operating Systems might not be in alignment with Microsoft's licensing policy. Consult Microsoft's licensing policy or your software supplier for details. Moreover, a client OS may present other limitations (for instance, the number of maximum concurrent TCP connections) compared to an server OS. |
