SYMPTOMS

Consider the following scenario:
  • You install the Network Policy and Access Services server role on a server that is running Windows Server 2008 Service Pack 2 (SP2) or Windows Server 2008 R2. The Network Policy Server (NPS) role service automatically becomes available on the server.
  • You configure the Ping User-Name registry entry on the server.
  • A client sends a RADIUS Access-Request packet to the server. The RADIUS Access-Request packet contains the specified user name that matches the value in Ping User-Name registry entry on the server.
In this scenario, the server does not send an Access-Reject packet to the client. Therefore, the client detects that the server is unavailable. However, the server is available.

Note The expected behavior is that the server sends the Access-Reject packet to the client.
