Is it recommended to install RADIUS (Network Policy and Access Services) on a domain controller or a non DC? I've read yes and no. I've also read that it is supposed to on a dedicated RADIUS server. Any information/recommendations are greatly appreciated. Thanks, Ryan

you can install RADIUS on domain controller without any problems. In any way any authentication request from RADIUS will be sent to domain controller.http://en-us.sysadmins.lv

Hi rdoss, Vadims is right .Based on my knowledge , you can install RADIUS\IAS\NPS on DC server without any problem. Here is an article for you reference : NPS Best Practices http://technet.microsoft.com/en-us/library/cc755120(WS.10).aspx Thanks.
