Before I start, here's the setup.
Freshly installed Win2k8 R2, fully updated with only AD DC, DNS and NPS roles installed. No additional software is installed, and all Microsoft firewalling and filtering is fully disabled in all locations I can find in the system.
I have attempted four or five different step-by-step walk throughs including Microsoft offerings in order to get a slew of RADIUS enabled devices to connect with no success. I've enabled logging of the NPS service for all events I can, and have used PortQry and netstat, however my problem seems to be the fact that none of the default ports are actively listening (eg, 1812-13, 1645-46). I have tried binding to the static ip, other ports, and anything else I could think of, but nothing I've attempted gets the NPS services responding. Event logs do not report any errors with services starting, and the NPS role event log filter shows zero results, so I'm sure the first problem is figuring out why the ports aren't open...
I have read multiple threads in this forum space including other sites. The common responses to this issue are "Check your firewall settings", "Disable your AV software" or any combination in between. Problem is, this never ends up correcting the issue for the original poster, and the threads end up "Still having this issue... any ideas?" or another user will ask "Did you ever get this resolved, because I'm having the same issue..." and no reply there after (even though it's been years since the last post). This leads me to believe that either the problem required a chat with an expert for money, or the solution was simple enough that the user didn't bother to post their fix at the end.
With all that said, do you guys have any recommendations of where to start? I appreciate any feedback...
