Network Policy Server keeps denying access to users. RRS feed

  • Question

  • Greetings!

    Windows Server 2008 R2 - Radius (NAP) Implementation. I configured everything as Microsoft is recommending but I keep receiving the same error logs from my W2008R2 Server. The Server is a Domain Controller also and has Certificate Services installed.

    The error is as follows :
