What is system requirements for NPS & how do I go about setting it up?

I am trying to research with no luck what all is required for NPS setup.
- I know I need a DC so it can access the AD.
- I know I need to install NPS role on a server.

However, I only want this service for my wireless network and nothing more.

Currently, I have ISA 2004 servers, I know ancient, serving as the firewall between my LAN & wireless LAN.  So, I am thinking I setup a NPS box then have the WAPs point to the NPS system's IP, configure WPA2-Enterprise authentication.  I will create a pass-thru for the NPS on the ISA server.  Then, not sure what else needs to be done.

But I only want it to be utilized by my wireless, not my LAN desktops.

Any ideas, suggestions?

Thanks in advance.

Requirements are Windows Server 2008 and at least 1 domain controller.  You can run NPS on the domain controller in very small environments but it isn't recommended.

Follow the NPA Step-By-Step guides (near the bottom of the page) to get yourself familiar with it in a test lab.

Depending on which features you want to implement you may need a Enterprise Root CA (which can run on a domain controller), multiple NICs in the NPA server, an internet connection, another NPS server at a remote location, etc...

So, I don't need to implement anything else, like NPA or anything right?  Just want to take the approach of less complex and less to implement the better.

Reason I ask this is, I am wondering if I should either do 2008 NPS  or should I do 2003 IAS for my RADIUS setup.

You do not need NAP unless you want to quarantine hosts that do not meet your security standards.  NPS works with NAP but does not require it.  As 2003 server is already 8 years old I suggest going with the 2008 sever solution.
