I guess that is a case only with W2K3STD where number of radius/aaa clients are limited to 50 only.
NPS provides different functionality depending on the edition of Windows Server 2008 that you install:
Windows Server 2008 Enterprise and Windows Server 2008 Datacenter. These server editions include NPS. With NPS in Windows Server 2008 Enterprise and Windows Server 2008 Datacenter, you can configure an unlimited number of RADIUS clients and remote RADIUS server groups. In addition, you can configure a group of RADIUS clients by specifying an IP address range.
Windows Server 2008 Standard. This server edition includes NPS. With NPS in Windows Server 2008 Standard, you can configure a maximum of 50 RADIUS clients and a maximum of two remote RADIUS server groups. You can define a RADIUS client by 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 NPS server uses the first IP address returned in the Domain Name System (DNS) query.
