SBS 2011 broken RADIUS auth via NAP RRS feed

  • Question

  • Hi All,

    I have a SBS 2011 on which I'm running the NAP role with an external firewall. The external firewall terminates PPTP connections, and uses the SBS 2011 NAP as a RADIUS authentication source. Due to a network reshuffle I had to change the IP address of the SBS. All services are now up & running great (AD, Exchange etc)  except for NAP.

    I used NTRadPing to test if the server is even responding to auth requests by passing a username in, and it looks like it doesn't respond at all. There are no erros shown in the Event viewer under "Network Policy Server". Further, nothing shows in the "Security" event log either. I'd have expected to see some audit failures at the very least.

    On the computer that I'm connecting from, I see error 718. It appears the problem is that the SBS isn't responding to auth requests.

    How can I further troubleshoot this, there are no errors in the event log!
