RADIUS

[roxanne]

Hi guys,

its my first attempt of creating RADIUS which is already installed on a windows server R2 standard edition.
I then configure this on a cisco switch, but no luck as to how its supposed to work and authenticate any ideas

The event log will tell you exactly why its failing. That will point you in the right direction. Also, your infrastructure is somewhat vaguely described--What part of the system is using Enterasys/Extreme Networks? Or is this a random "how to get NPS to work with Cisco" thread?

You also didn't describe the authentication mechanism--MAC auth, LDAP, 802.1x, ect... If you go into more detail we can probably address your problem more specifically.

You can always go to your event viewer and see why NPS is failing.

Great thank you 

That should cover it all...

The first link in the list looks promising - I haven't configured a C in a long time.
