note

RADIUS Server on Windows Small Business Server

When you install a RADIUS Server on Windows Small Business Server 2008 or 2011, change the default NPS port from 1812 to 1645. Verify that no processes are listening on port 1812 before installing ESA by running the following command: C:\> netstat -a -p udp | more

Alternatively, when installing ESA RADIUS, change the RADIUS port in the Advanced configuration screen.


note

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.
