In Event Viewer - Network Policy and Access Services I get the following Error code message:
A RADIUS message with the Code field set to 12, which is not valid, was received on port 1812 from RADIUS client XN08_C1H2. Valid values of the RADIUS Code field are documented in RFC 2865.
We have serveral devices that send this request and the server never response. This event fills our logs and is very anonying. The Device manufacture suggest using a Linux Server that will accept and return the proper status from this field.
I realize that this RFC 2865 makes this optional but other products are supporting this Option and it would be nice to have it support in Windows 2008 Server.
