RADIUS Server setup in Windows

I need to setup a RADIUS server for the wireless authentication and have no idea where to begin, even after reading http://www.windowsnetworking.com/kbase/WindowsTips/Windows2000/AdminTips/Security/SettingupWindows2000Radiustoauthenticatewireless802.1xclients.html.

I am on Windows 2003, and wanted to ensure that 2003 IS the RAIUS server and that one does not need 3rd party software or an additional server just for RADIUS.

How can this be done?

Do you have a wireless controller?

You only need Windows Server 2003 and an access point that supports RADIUS. In order to enable RADIUS you have to add the service from add remove programs > windows components on the server. The service is IAS. You will wan to follow the doc you have linked above for the config if you have not had experience with it before and are using Active Directory. Basically what it boils down to is defining the wireless AP or controller (whichever you have) as a client and setting a shared secret that you will set on the AP when you point it to the IAS server. You will have to define the Users / groups that you want to have access and then define the IAS server on the AP as a AAA server with RADIUS as the communication method. If you would like to post the model of your wireless controller or AP, I may be able to do step by step.

Once your Radius server is set up as mentioned above, you will need to configure your wireless settings as shown in figure 3-19 on page 15 in the document at http://downloads.linksysbycisco.com/downloads/WRT54GS-EU_v6_UG_efgn,0.pdf You will replace the radius server IP with the one you just set up and the port with 1812 if the IAS is not on a domain controller. If it is the port is 2012. you will need to input the key you set when creating the client record in IAS. That should be it. that is the two components. If you run into any questions, please let me know.

ciscoguy69: This solution appears to be the one that would work, but we decide to go a different route in regards to the radius setup...  THANK YOU either way for a much simpler solution that I will be implementing at another location though!
