IAS reportedly only supports 50 users for radius ?  Is this accurate ?  If so, is there a alternate third party radius server that will run on W2K3 ?

You can configure IAS in Windows Server 2003, Standard Edition, with a maximum of 50 RADIUS clients and a maximum of 2 remote RADIUS server groups. You can define a RADIUS client using a fully qualified domain name or an IP address, but you cannot define groups of RADIUS clients by specifying an IP address range. If the fully qualified domain name of a RADIUS client resolves to multiple IP addresses, the IAS server uses the first IP address returned in the DNS query. With IAS in Windows Server 2003, Enterprise Edition, and Windows Server 2003, Datacenter Edition, you can configure an unlimited number of RADIUS clients and remote RADIUS server groups. In addition, you can configure RADIUS clients by specifying an IP address range.

When you say "only supports 50 users", are you talking about 50 incoming user connections or 50 devices (clients) that users would connect to?  

IAS in Windows Server 2003 Standard is limited to 50 clients, but clients are not users.  Radius clients are the devices that a user would use Radius to connect to (such as a VPN server).  As far as I know, the IAS Radius server can authenticate an unlimited number of users for these 50 Radius Clients.

Can you confirm that you want more than 50 Radius Clients instead of 50 Radius users?

Actually, I only have 1 device that would leverage radius for authentication.

Ok, then this "device" is your one and only "Radius Client".  So you have 49 spots left!

I'm guessing then that this IAS Radius server will do the trick for you then.
