The Windows 2008 Radius NPS Server is not communicating with the Lan Enforcer
The packet capture on the Lan Enforcer shows that the Lan Enforcer is sending a Radius packet to the Radius server, but the Radius server is not replying.
The System Event logs on the Radius Server has the message "A RADIUS message was received from the invalid RADIUS client IP address of 10.x.x.x.
This message usually means that the client at IP address 10.x.x.x is not authorized to communciate with the Radius Sever. Make sure that the devices the Radius Server is required to communicate with are configured on the Radius Sever.
In this particular case, during the initial testing without the Lan Enforcer, the Radius Server was configured to only communicate with the Authenticator (Switch). After the Lan Enforcer was added back in, the Radius Server was not configured to communicate with the Lan Enforcer.
