  1. nice guide. this page was the 4th ranked page when i googled “server 2012 r2 radius” so i think you may want to consider cleaning up the screenshots. even clicking to the bigger images was like looking at them through a wet paper towel

    • the pictures are just small. I’ve to redo the pictures which will be done in the up coming days. How ever it’s not much difference with a configuration on Windows server 2008 R2 :)

    • It’s a nice blog unfortunately, I need to use a translator for it to read this blog post :)
      When you need such setup it’s great to use.

  3. Do you know if it possible to apply certain policies to certain clients, ie I want AD Group X to be able to authenticate on client X and AD group Y to be able to authenticate on client Y and so on?

    • In the Small Business Server edition of 2008 and 2011 you are able to select where a user can connect to a computer. At the moment I am unable to look for this policy.

  4. The prompt after clicking “Register Service in Active Directory” says “clients must be authorized to read dial-in properties, etc.” Is it assumed my clients are authorized if they’re in the user list, or should I make sure some other setting is right first? Up until now, we’ve only used AD as authentication for a bunch of Macs to get on Windows Remote Desktop. I don’t want to kick everyone out and have to scramble to undo what I did. Thanks,


    ps. GREAT GUIDE!

    • Jeff, there you choose how to say that clients can authenticate. If you create a security group in the Active Directory, it will be easier to maintain. Otherwise you need to change the dial-in properties of every user.

      I think the best solution for you is to create a security group > put the users in there > add group to the radius settings and your done. You don’t need to change the dial-in properties.

      I hope this will help you.

  5. we use Dlink DWC2000 controller & 8610 AP, on Windows Radius server ” Radius Clients” , should we add all AP ip address or only controller ip is sufficient ?

    • It depends on the brand. for example a cisco wlan controller it’s not needed while for a netgear wlan controller you need to add all AP’s to the radius setup

      • what do you recommend, irrespective of bands ? should we add AP also in Radius Clients.
        At the moment with controller its working, so cross checking.

  6. If it’s working now only with the controller installated. it’s not need to change it. ulease the vendor expliciet recommends it in it’s documentation for example the AP’s of netger we have running in our office are basically standalone but connected to the wlan controller this is why we need to add the ap’s of netgear to the radius.

    • users are able to connect to Radius & users gets ip address also, but sometimes users are facing disconnection & connectivity with APIPA Ip address.
      What could be reason for users getting APIPA IP, we have sufficient ip address on DHCP pool.
      With WPA2 we don’t have such APIPA issue, with radius we are seeing this random APIPA issues.
