We had to configure RADIUS authentication on multiple servers 2008r2 / 2012 and 2016
On some of the servers we had already Routing and Remote access service running.
When we opened the console it already showed RADIUS ..?
So we where under the impression that this was already installed as part of the Routing and Remote Access Service
But when trying to authenticate nothing was happening …
After al long time trying to figure out what was wrong, we noticed this …. ?
Even if we could open and configure the RADIUS Client config, it was not installed or running …
Make sure the Network Policy Server is installed and running
You need to see the Service Running
You will see NPS appearing in the Server Manager too afterwards
Windows 2012 / 2016 see here :
Check the NPS service is running :
No you are ready to configure the RADIUS client policy setup.
And test the the VPN access …
TIP : Don’t forget to give the AD user Access Permissions
